TYPIFICATION OF SOME NAMES IN THE CRUCIFERAE, MOSTLY FROM NORTH ASIA
ТИПИФИКАЦИЯ НАЗВАНИЙ НЕКОТОРЫХ, ПРЕИМУЩЕСТВЕННО СЕВЕРОАЗИАТСКИХ, КРЕСТОЦВЕТНЫХ (CRUCIFERAE)
Summary. The data on type specimens of 20 names of Cruciferae taxa described predominantly from North Asia are given. For all of them, lectotypes are designated, in six cases correcting previous typifications. Selected names published by A.A. Bunge, N.A. Busch, A.P. de Candolle, G.S. Karelin and I.P. Kirilov, M. Kitagawa, J. Mayer, C.F. Ledebour, E. Regel, B.K. Schischkin, and C.L. Wildenow are treated irrespective of being currently accepted or not, including three illegitimate names for which automatic typification is not applicable. Except for Dimorphostemon Kitag., the names of species and infraspecific taxa are in the focus.
Key words: Brassicaceae, name, nomenclature, Siberia.
Аннотация. В заметке приведена информация о типовых образцах 20 названий, установленных преимущественно для североазиатских крестоцветных (Cruciferae) А.А. Бунге, Н.А. Бушем, О.П. Декандолем, Г.С. Карелиным и И.П. Кириловым, М. Китагавой, Э. Регелем, Б.К. Шишкиным и К.Л. Вильденовым. Все они (в том числе шесть названий, некорректно типифицированных прежде) лектотипифицированы, независимо от того, принимаются ли современной систематикой или числятся в синонимах, включая три незаконных названия, к которым автоматическая типификация неприменима. За исключением Dimorphostemon Kitag., рассмотрены названия видового и внутривидового ранга.

asper is not only illegitimate under ICBN Art. 52 (McNeill et al., 2006), but also includes types of both mentioned names, one of which should be chosen as lectotype for both D. asper and Dimorphostemon.
Exactly the same reasons prevent accepting the later designation of D. pectinatus as a type of Dimorphostemon by Golubkova (l. c.). The widely used epithet "pectinatus" has been introduced by Candolle while establishing the binominal Sisymb-rium pectinatum DC. (Candolle, 1821 : 485). Both earlier published legitimate names, Cheiranthus pin-natifidus and Hesperis pinnata, were cited as well, and even if such re-naming is treated as an intention to avoid creation of a later homonym of Sisymbrium pinnatifidum (Lam.) DC., the name S. pectinatum is still superfluous as soon as there were no reasons not to use Persoon's binominal as a basionym for the combination in Sisymbrium L. As a result, the name S. pectinatum includes the same types of the two earlier published legitimate names as D. asper.
The name Dimorphostemon is typified here by the type of the earlier of the two potentially applicable names, Cheiranthus pinnatifidus, which is based on the holotype deposited in B: "Sibiria, [fl.], [misit] Stephan" (B-W 12111!). The same element is designated here as a lectotype for the illegitimate Dimorphostemon asper Kitag., Dontostemon asper Schischk. and Sisymbrium pectinatum DC. (previous typification of the latter name by Golubkova (1. c. : 126) has no taxonomical power). Two other names enumerated by the above cited authors, Hesperis punctata Poir. and H. pilosa Poir., both illegitimate because of having Cheiranthus pinnatifidus cited as a synonym in the protologues, are automatically typified by the same specimen (ICBN Art. 7.5, McNeill et al., 2006).
The name "Alaida Dvorak" is often mentioned as an illegitimate synonym of Dimorphoste-mon and/or Dontostemon (e. g., Al-Shehbaz, Ohba, 2001; Golubkova, 1974, 1976). However, "Alaida" is likely not to be a validly published name under ICBN Art. 37.1 and 37.3 (McNeill et al., 2006) as soon as its type was not indicated in the original publication (Dvorak, 1971), and I have no information regarding such indication in any subsequent work (conf. Farr, Zijlstra, 1996+).
Alyssum alpestre L. var. orbiculare Regel, 1861, Bull. Soc. Nat. Mosc. - A. orbiculare (Regel) Nyar., 1938, Bul. Grad. Bot. Muz. Bot. Univ. Cluj, 18 (1-4) : 97, nom. illeg., non Timb. et Jeanb., 1884-1885 [=A. obovatum (C.A. Mey.) Turcz. subsp. orbiculare (Regel) Peschkova].
Described from E Siberia: "Ostsibirien (Stubendorff)" (Regel, l. c.).
Lectotype (hic designatus) [Russia, E Siberia, Yakutiya (Sakha)]: "Alyssum alpestre L. ß orbiculare. Teste Rgl. Nr. 24b. In itinire ad Kamtsch[atka, 1849], [fl., fr.], Dr. Stubendorff" (LE!).
Other original material (isolectotype?): "Alyssum alpestre L. orbiculare. Teste Rgl. Nr. 24b. In itinire ad Kamtsch[atka, 1849], [fl., fr.], Dr. Stubendorff" (LE!).
Most likely, both lectotype and assumed isolectotype are duplicates of the specimen: "Dr. Stubendorff. It. Kamtschat. 1849. № 24. 24/V, [fl., fr. sic.], Lena. Alyssum lenense Ad." (LE!). Regel apparently did not study this specimen: unlike in the first two cases, there are no Regel's handwritings on its label, and A. lenense is reported only "Im Juni mit Blumen und Früchten" (Regel, l. c. : 179). Therefore, original material on Alyssum alpestre var. orbiculare is likely to be represented by these three specimens (and not another two, № 123 and № 156, stored in the same folder).
Alyssum dasycarpum Steph. ex Willd. 1800, Sp. Pl. 3 : 469.
Described from pre-Caspian deserts: "Habitat in Sibiria ad Kamam [Kumam] et Volgam flu-vium" (Willdenow, l. c. : 470).
Lectotype (hic designatus): [Russia, most likely Astrachan prov.]: "Alyssum dasycarpum ... Habitat inter Kamam et Wolgam fluvium, [fl., fr. prim.]" (B-W 11918-4!).
Other original material: [the same label, fl., fr.] (B-W 11918-2!, B-W 11918-3!).
Possible original material: "Alyssum dasycarpum. Willdenow dedit Ottoni. Sibiria, [fl., fr.], Herb. Otto" (B 10 0241645!); "Sibiria, [fl., fr.], P.S. Pallas" (BM 000583333) [seen at low resolution via plants.jstor.org]; "10. In desertis arenosis provenit copiose aprili florens, [fl., fr. prim.], Sokolow" (LE!).
"Kama" apparently represents a misspelling (originating from Stephan's label) because the species does not occur in Kama basin or Volga-Kama interfluves; it should be applied to the river Kuma, as improved by Candolle (l. c. : 318).
The type of A. dasycarpum was previously designated as "Type: in Sibiria ad Kamam et Wolgam fluvium, Stephan (holo. LE, iso BM!, G!, K!)" by Dudley (1965 : 375; 1968 : 153). Thorough search of the specimen with such a label or at least originating from the herbarium of Stephan in LE gave no results. The only gathering in LE which could be a duplicate of any of Willdenow's
specimens is the above collection of N.P. Sokolov, a member of Pallas's expedition explored pre-Caspian deserts in spring and early summer 1773 (Pallas, 1776; Sytin, 1997). Apparently, this specimen can not be treated as lectotype and even if any specimen from the herbarium of Stephan is found in LE, those in B have priority as the validating (Willdenow's) description was based on the samples from B-W. In addition to the cited above Willdenow's folder label, the following original labels glued inside the folder belong to the original material: "Alyssum (Mönchia) dasycarpum. Kama et Volga. Caules plures ex 1 radice (Stephan)"; "Species mihi ignota ... ab affini Alysso campestri, foli. latissima et styli fruct... lon-gissima distinguenda ... Alyssum calycinum variet. [Stephan]"; "Alyssum minimum? Clypeola [stricken out] ad Nitrariam officinam supra Astrachaniam fre-quensiss[ima]. (Pallas)". One more specimen stored in this folder, B-W 11918-1, represent A. tur-kestanicum Regel et Schmalh. (widely known under the name A. desertorum Stapf).
Regarding other specimens annotated and reported by Dudley (l. c.) as isotypes, the one in Kew, bearing the only label "Psilonema dasycarpum nob." (K 000697044; seen at The [Kew] Herbarium Catalogue, 2006) is a later (1826) gathering of C.A. Meyer from NE Kazakhstan. Preliminary search of relevant material in G gave no result; probably, the specimen "Alyssum dasycarpum W. Astrachan, [fl., fr.], m. Steven 1820" (G-DC: G 00205604!) was meant but its attribution to the original material is far not obvious.
Andreoskia dentata Bunge, 1833, Enum. Pl. Chin. Bor. : 6 [= Dontostemon dentatus (Bunge) Ledeb.].
Described from N China: "Hab. rarior in collibus apricis prope Pan-schan montium orienta-lium" (Bunge, 1. c.).
Lectotype (hic designatus): [China, east of Beijing]: "Andreoskia dentata mihi. Chin. bor., [fl.], 1831. B[unge]" (P 02272588!).
Isolectotype: "China, [fl., fr. prim.], D. Bunge. 1831" (LE!).
Arabis glandulosa Kar. et Kir. 1842, Bull. Soc. Nat. Mosc. 15, 1 : 146. - Dimorphostemon glandulosus (Kar. et Kir.) V. Golubk. 1974, Bot. Zhurn. (Moscow & Leningrad), 59, 10 : 1453. - "Alai-da glandulosa" (Kar. et Kir.) Dvorak, 1971, Feddes Repert., 82 (6) : 431 [= Dontostemon glandulosus (Kar. et Kir.) O.E. Schulz].
Described from SE Kazakhstan: "Hab. in lapidosis subalpinis Alatau ad fl. Sarchan, rarissima. Florentem et fructiferam medio Julio invenimus" (Karelin, Kirilow, l. c.).
Lectotype (hic designatus): [Kazakhstan, Almaty prov.]: "1231. K. K., [fr.], Herb. Fischer" (LE!).
Isolectotypes: "Arabis glandulosa Kar. et Kir. In lapidosis subalpinis Alatau ad fl. Sarchan fl. et fr. medio Julio, [defl., fr.], Kar. et Kir. 1841" (KW!); "1231. Arabis glandulosa Kar. et Kir. In lapidosis subalpinis Alatau ad fl. Sarchan leg. Karelin et Kiriloff a. 1841, [fr.], Soc. Imp. Nat. Mosq. Reliq. Ledebour"; "Sisymbrium glandulosum K. et K. Arabis glandulosa Kar. et Kir.: Altai. Kar. et Kir. coll. n 1231, [defl., fr.], [Herb. Turczaninow]"; "Songaria. Arabis glandulosa Kar. et Kir. Alatau / Arabis glandulosa Kar. et Kir. In lapidosis subalpin-is Alatau ad fl. Sarchan, rarissima, florentem et fructiferam medio Julio invenimus. № 67, [fr.], 1841. Kar. et Kir." (LE!).
The first attempt to designate the type of Arabis glandulosa was undertaken by Golubkova (1976 : 128-129) who cited relevant part of the pro-tologue and published a photo of the specimen annotated by her on February 1972 as "typus!". This specimen, however, does not belong to the original material which is evident from its label written by S.S. Stchegleyev: "Arabis glandulosa Kar. et Kir. enum. 1841. № 67. 1842 una cum Sisymbrio sophia L." (LE!). Along with one more specimen in LE, this plant was obviously collected in 1842 by G.S. Karelin alone who visited during his stay in Semi-palatinsk in 1842-1844 many localities where he worked together with I.P. Kirilow in previous two years and repeated a number of their joint collections.
Later, Gubanov et al. (1998 : 27) cited the type as follows: "Typus: "In lapidosis subalpinis Alatau ad fl. Sarchan". Lectotypus (LE): "a. 1841, № 1231" - designated by Golubkova in February 1972". Here, citation from the protologue is again correct but reference to the specimen chosen by Golubkova as type (i. e., as lectotype) is direct and explicit and therefore cannot be taken as an improvement of Golubkova's incorrect typification.
Here, the specimen with the only label bearing original (authors') indication "1231" is designated as lectotype. Different numbers (1231 and 67) on the labels of isolectotypes reflect initial (field) and subsequent (published) numbering of the same collection. The first isolectotype is mounted on one sheet with lectotype and, representing the same col-
lection, can be treated as its part as the whole sheet fits the definition of a specimen (ICBN Art. 8.2; McNeill et al., 2006).
Borodinia baicalensis N. Busch, 1921, No-tul. Syst. Herb. Hort. Bot. Petrop. 2, 35 : 137 [= B. macrophylla (Turcz.) O.E. Schulz].
Described from eastern shore of Baikal: "Transbaicalia, distr. Bargusin. Litus lac. Baical, peninsula Swjatoj Nos.

(Busch, l. c. : 138).
Lectotype (hic designatus): [Russia, E Siberia, Buryatiya]: "Transbaikalskaya prov., Barguzin-sky distr., Baikal shore, lake Sor. Golets in the upper reaches of M[alyi] Chiverkui. Stony slope, in crevices, abundant from 1200-1300 m a.s.l. № 11. 27 V 1916, [fl.], I. Larin & G. Kanevsky" (LE!).
Syntypes: "Transbaikalskaya prov., Bargu-zinsky distr. Baikal shore, Saint Nose peninsula. Go-lets in sources of Baltai, on the top, between stones, often. № 18. 2 VI 1916, [fr. immat.], I. Larin & G. Kanevsky"; "Transbaikalskaya prov., Barguzinsky distr. Baikal shore. Goltsy at 1200 m a.s.l. Sandy and gravelly slope and rock crevices, abundant. 27 V 1916, fl., I. Larin & G. Kanevsky" (3); "Transbaikalskaya prov., Barguzinsky distr. Baikal shore. Goltsy at 1200 m a.s.l. Sandy and gravelly slope and rock crevices, abundant. 9 VI 1916, fr. imm., I. Larin & G. Kanevsky" (3) (all - LE!).
Original material consists of four gatherings; lectotype and first syntype are mounted each on a separate sheet while the rest of six syntypes representing two gatherings are mounted in pairs on three sheets; each such sheet is supplied with a label: "Transbaikalia, Barguzin, Sv[yatoi] Nos peninsula, Baikal shore. Goltsy at 1200 a.s.l. Sandy and gravelly slope and rock crevices, abundant. I. Larin & G. Kamensky. 27 V [19]16 fl.; 9 VI [19]16 fr. imm.". This label was cited by A.N. Berkutenko first as "type specimen" (Berkutenko, 1982 : 105) and later as lectotype (Berkutenko, 2003 : 129) and one of three relevant sheets was annotated by her on 11 December 2001 as "lectotypus". Representing a mixture of two collections (one plant in bloom and
two with young fruits), this sheet cannot be taken as lectotype because no specimen as determined by ICBN Art. 8.2 (McNeill et al., 2006) has been designated as type.
The specimen represented by a single plant pictured in the original publication (Busch, 1921 : 141) supplied with a label bearing author's identification is taken here as lectotype.
Braya tilingii Regel, 1859, Nouv. Mem. Soc. Nat. Mosc. 11 : 61. - Borodinia tilingii (Regel) Berkut., 1982, Novit. Syst. Plant. Vasc., 19 : 106. -Arabis tilingii (Regel) Berkut., 2003, Bot. Zhurn. (St. Petersburg) 88 (11) : 132 [= Borodinia macrophylla (Turcz.) O.E. Schulz].
Described from the western shore of Okhotsk sea (Ayan): "Habitat in montibus et collibus sterilibus [Ajanensis]" (Regel, Tiling, 1859).
Lectotype (Berkutenko, 1982 : 105; id., 2003 : 133, "typus"; German & Berkutenko, hic designatus): [Russia, Far East, Khabarovsk prov.]: "Draba [struck out] Braya tilingii Rgl. (Fl. ajan. № 47). Prope Ajan in montibus et collibus sterilibus legit Tiling, [fl., fr. immat.], v. s. Rgl. [stamped]: Herbarium Trautvetter" (LE!).
Isolectotype: "Braya tilingii Rgl. Rgl. et Tiling, fl. ajan. N. 47. Prope Ajan legit Tiling, [fl., fr. immat.], v. s. Regel" (LE!).
Berkutenko (1982 : 105; 2003 : 133) twice cited the specimen designated here as lectotype but it did never resulted in a typification as determined by the ICBN. In the first case, both samples, hereafter lectotype and isolectotype, were cited as "type specimens"; in the subsequent publication, the first specimen was explicitly designated as type but requirements of ICBN Art. 7.11 and 9.21 of (McNeill et al., 2006) were not met.
Cardamine lyrata Bunge, 1833, Enum. Pl. Chin. Bor. : 5.
Described from N China: "Hab. in humidis ad rivulum pr. Ssi-jüi-ssy" (Bunge, 1. c.).
Lectotype (hic designatus): [China, vicin. of Beijing]: "Cardamine lyrata Bge. Chin. bor., [fl., fr. prim.], 1831. B[unge]" (P 00747521!).
Isolectotypes: "Cardamine lyrata m. Ch. b., [generative part absent], M[isit]. Bunge"; "Cardamine lyrata Bge. Ch. b., [fl.], Bunge (Herb. Fischer)" (LE!); "Cardamine lyrata mihi. Chin. bor., [fl.], 1831. Bunge" (P 00747520!).
Lectotype is represented by two plants, isolectotypes by one each; isolectotypes in LE are mounted on one herbarium sheet and could be trea-
ted as one specimen. All original labels are written by Al. Bunge; few technical details are added later.
Cheiranthus fruticulosus J. Mayer, 1786, Abh. Böhm. Ges. Wiss. (Math.-Nat.), 2 : 237, tab. 7, fig. 2, nom. illeg., non L., 1753 [= Stevenia cheiran-thoides DC. subsp. incarnata (DC.) D. German].
Described from S Siberia: "Diese Pflanze mohnet an trockenen Orten in Sibirien ... in Sibiriae siccioribus" (Mayer, 1786 : 238).
Lectotype (hic designatus): [Russia, S Siberia, most likely Krasnoyarsk prov. or Khakassia]: "Fig. II. Cheiranthus fruticulosus; foliis linearibus integerrimis, caule ramoso, pedunculis glabris, siliquis virgatis, [fl.] / Ex herbario Meyeriano" (PR!).
Other original material: "Hesperis caule ramosissimo, foliis linearibus, pedunculis glabris. Flor. Sib. Tom III. p. 262, [fl., fr.] / Ex herbario Meyeriano" (PR!).
Both specimens are represented by the single plant each and both are pictured in the original publication (complete first plant and upper part of infructescence of the second one). However, the second specimen is not treated as a syntype because it is not cited by Mayer; its label is written by A.W. Martini, a companion of J.G. Gmelin at the last stage (since 1740) of his famous Siberian journey (Litwinow, 1909). The same material should be regarded as a source of the lectotype of Hesperis rupestris Pall. (German, forthcoming).
Cochlearia sisymbrioides DC. 1821, Reg. Veg. Syst. Nat. 2 : 368 [= Armoracia sisymbrioides (DC.) Cajand.].
Described from NE Siberia: "Hab. in Sibiria ad littora maris glacialis et ad Lenam fluvium (Adams ex Fisch. v. s. sp.)" (Candolle, 1821).
Lectotype (hic designatus): [Russia, NE Siberia, Yakutiya (Sakha)]: "E littoral mar. glacialis, Adams [1806], [fl., fr. prim.], m. Steven. 1820" (GDC: G00202192!).
Syntype: "... Cl. Adams ad Lenam fl[uvium], [fl., fr. prim.], mr. Fischer 1819" (G-DC: G00202147!).
Both samples are mounted on one herbarium
sheet.
Other collections of the species definitely or presumably made by Adams during his famous trip in 1806, are deposited in herbaria of St. Petersburg and Moscow: "№ 83 ... Tetradynam..., am ... Mammouth vorzüglich häufig ... an Erysimum? Byk-mys [= Bykovsky cape], [buds]"; "№ 82. Cochlearia an macrophylla an species nova? In . ab . Lenea
[Lenae], [fr. mat.]" (MW); "Herb. Fischer, [sine data, fl.]"; "Cochl., [fl., fr. prim.], Herb. Fischer" (LE).
Some of these specimens, especially with flowers and young fruits, might represent duplicates of lecto- and/or syntype of C. sisymbrioides.
Dentaria tenuifolia Ledeb. 1815, Mem. Acad. Sci. Petersb. 5, 5 : 547 [= Cardamine trifida (Lam. ex Poir.) B.M.G. Jones].
Described from Siberia: "Hab. in Sibiria a Tomo fluvio ad Lenam usque fluvium" (Ledebour, l. c. : 548).
Lectotype (hic designatus): "Dentaria tenuifolia mihi. In Sibiria a Tomo fluvio ad Lenam usque ... Tilesii, [fl., fr. prim.], 6 [Aug.? 18]13" (LE!).
Other type material: image "Tab. LXV [Cardamine foliis trifidis acutis, laciniis integris vel incises, caule erecto]" (Gmelin, 1768).
The text of the lectotype label generally repeats the distribution given in Gmelin (l. c. : 272) who's description was used by Ledebour (e. g., for characterization of the underground organs) and should be treated also as validating. Therefore, both Gmelin's illustration and specimens belong to the original material from which only the picture was available for the present study.
The following specimen is also worthy of mentioning: "Dentaria tenuifolia mihi, [fl.], ad Lenam" (KW!) with the label written by Ledebour.
Isatis oblongata DC. 1821, Reg. Veg. Syst. Nat. 2 : 571.
Described from SE Siberia: "Hab. verosimili-ter in Sibiria Ircutensi unde semina missa fuerant ad cl. Steven (v. s. c. in h. Nikitensi)" (Candolle, l. c. : 572).
Lectotype (hic designatus): "Culta in H.[ortus] Nikitensis e seminibus sibiricis, Ircutia missis, [fr.], Mis. Steven. 1820" (G-DC: G00206196!).
Syntype: [the same label, fl.] (G-DC: G00206164!).
Possible original material: "Isatis oblongata, [fl., fr.]. Cult. Nik. ex sem. Ircut." (LE!).
Both elements in G (upper part of stem with fruits and complete plant with flowers) are mounted on the same sheet and share one label. From their habit and phenological state it is very likely that they do not represent one collection; therefore, lec-totypification is proposed.
The envelope "In Ircutia m. Steven" with the seeds apparently of the same origin, from which the plants treated by Candolle were grown, is mounted on another herbarium sheet in LE along with plants grown from these seeds in the botanical garden of Tartu.
Isatis tinctoria L. subsp. jacutensis N. Busch, 1913, Fl. Sib. et Orient. Extrim. 1 : 159 [= Isatis jacutensis (N. Busch) N. Busch].
Described from NE Siberia: "Yakut[skaya prov.]. Yak[utsky distr.]. Yakutsk. Hb. Ak[ademiae Scientarum Petropolitanae]! Gar' near Bestyakhs-kaya, along Amginsky road. Drob[ov]!

Lectotype (hic designatus) and isolectotype: [Russia, NE Siberia, Yakutiya (Sakha)]: "Ad fluvium Lenam inferiorem, prope pagum Ssiktjach, [fr. pro more mat.], 24 Julii 1875. Czekanowski" (LE!).
Syntypes: "Jakutsk, 17 VI, [sine coll., fl., fr. prim.]"; "Yakutskaya prov. and vicin., ashes near the station Bestyakhskaya at Amginsky road. № 42. 8. VI. 1912, [fl.], W.P.

Bunge 8-9 Jul. 1885" (all - LE!).
Isolectotype is represented by three racemes apparently taken from the lectotype mounted together with one of Bunge's specimens represented by one inflorescence; the sheet originates, according to the stamp, from "Herbarium Trautvetter".
Lepidium amplexicaule Willd. 1800, Sp. Pl.
3 : 436.
Described (fide Busch, 1939 : 516, based evidently on the information of Georgi, 1802 : 285) from Irtysch valley [in NE Kazakhstan]: "Habitat in Sibiria" (Willdenow, l. c.).
Lectotype (hic designatus): "Lepidium amplexicaule W., [defl., fr.; fragm. ex herb. Willd.]" (GDC: G00203941!).
Possible isolectotypes: "Lepidium obtu-sifolium [stricken out] Stev. amplexicaule W. L. cordatum W. Herb. obs. Stev. Sibiria. Salesow, [fl., fr.] Herb. W. Besser / Herbarium Andrzeiofskii 1841" (KW!); "Lepidium amplexicaule. Ex Sibiria, [defl., fr.], Comm. Stephan. Remitte! [M. v. Bieberstein]" (LE!).
The holotype specimen was expected to be deposited in Willdenow's herbarium in B (e. g., Busch, l. c.); however, no material on L. amplexi-caule has been found by the present author in either B-W or in general collection of B which is in agreement with the absence of relevant specimen in the online database of Berlin-Dahlem (Röpert, 2000-). The specimen (upper portion of one branch, less than 10 cm long) in G-DC apparently representing a part of original Willdenow's one (but not the whole specimen described as branched plant ca. foot tall) obtained by Candolle via Ch. Steven is designated here as lectotype.
Lepidium affine Ledeb. 1821, Ind. Sem. Horti Dorpat., App. 1 : 22.
Described based on the plants grown from seeds in the Botanical Garden of Tartu; no information was given in the original publication (Lede-bour, 1821) regarding the origin of seed material but morphology it typical for Siberian specimens. It is likely that the species, often treated as L. latifolium L. subsp. sibiricum Thell., is restricted to North Asia and its reports from other regions belong to other taxa.
Lectotype (hic designatus): "Lepidium affine mihi, [fr.], H[ortus]. D[orpatensis]. [18]20. [C.F. Ledebour]" (LE!).
Several other specimens in LE might potentially belong to the original material, including: "Cult. in horto botanico dorpatensi s: diu, nom. Lep. sibirici et L. affinis. Fl. Junio, [fr.], Hb. Meyer" and unannotated specimens from Fischer's herbarium.
Lepidium cordatum Willd. ex Steven, 1821, in DC. Reg. Veg. Syst. Nat. 2 : 554.
Described from Siberia, very likely from Altai: "Hab. in Sibiria" (Candolle, l. c.).
Lectotype (hic designatus): "Habitat in Sibiria, [fl., fr. prim.], [comm.] Bieberstein. W[illdenow]." (B-W 11817!).
Possible isolectotypes: "Lepidium obtusi-folium novum, [fl., fr. prim.] e Sibiria, Salesow" (KW!); "Lepidium obtusifolium nov., [fl., fr. prim.], Ex Sibiria, Salesow. remitte! [Added later:] = L. cor-datum herb. Willd. ex Stev. Dec. syst."; "Lepidium amplexicaule, [defl., fr.], [Herb. Stephan №] 804. Salesow. Sibiria." (LE!).
Candolle (l. c.) apparently had seen no material on this species prior to publishing the proto-logue, and placed it among "species non satis notae"; description was based on the information provided by Steven. One of the two mentioned elements is a specimen obtained by Willdenow from Bieberstein, is chosen as lectotype. The second element, "L. amplexicaule. Stev. herb. non Willd.", was not available for this study and probably is to be found in collection of Steven in H. It is noteworthy that the cited specimen from Stephan's herbarium is also initially determined as L. amplexicaule: could not it be Steven's identification? Among two specimens signed as "Lepidium obtusifolium", the one in LE has the label written by Bieberstein who probably is the author of this nomen nudum. Habit, condition and phenophase of all specimens are very similar to those of the lectotype.
Thlaspi cartilagineum J. Mayer, 1786, Abh. Böhm. Ges. Wiss. (Math.-Nat.), 2 : 235, tab. 7, fig. 1 [= Lepidium cartilagineum (J. Mayer) Thell.].
Described from SW Siberia: "Dr. D. [A.W.] Martini hat diese Pflanze in der verlassenen Bara-benser Steppen an salzigten Orten häufig gefunden. ... In deserto Barabensi locis salinis abunde crescit" (Mayer, 1786 : 237).
Lectotype (hic designatus): [Russia, SW Siberia, most likely Novosibirsk prov.]: "Fig. 1. Thlaspi cartilagineum; capsulis subrotundis integris, fo-liis ovatolanceolatis cartilagineis, [fl., fr. prim.] / Ex herbario Meyeriano" (PR!).
Other original material: "Thlaspi foliis ex ovato-lanceolatis cartilagineis, capsulis subrotundis integris. Fl. Sib. Suppl. [buds]" (PR!).
The single plant representing the lectotype is pictured in the original publication. Like in the
above case of Cheiranthus fruticulosus, the second specimen (its label is written by Martini) is not treated as a syntype because it is not cited although the polynominal from the protologue appearing on the label of the lectotype apparently derived from Martini's label. J.G. Gmelin is obviously the author of this original polynominal.
The very similar label (with the only difference in "Gmel. sen." instead of "Fl. Sib. Suppl."), also by Martini, is glued on one sheet in LE where another two specimens of L. cartilarineum are mounted, both grown from seeds collected by P.S. Pallas (herb. Pott). Cultivars are represented by one complete plant and another one lacking the root; most likely, five separately mounted rosette leaves also belong there. Martini's label might only refer to a small envelope with very few plant remnants which than represents another element of the original material; otherwise this is just a label not accompanied by any specimen.
Another two specimens labeled as "In salsis deserti Barabensis et ad fluv. Irtim frequens", both with ripen fruits (LE), apparently represent later collections where Martini's distribution is updated by that of Pallas who's collections from Irtysch annotated by him as "L. ascendens Pall." (nom. nud.) are also stored in LE.
Surprisingly enough, no specimens of L. cartilarineum and other Siberian Cruciferae collected by Gmelin and Martini were found in STU where Martini's collection is deposited.
Comparison of the original material and other Siberian gatherings of L. cartilarineum with authentic specimens of L. crassifolium Waldst. et Kit. (B!, MW!, PR!) confirms their apparent con-specificity.
The author is grateful to the curators and staff of all mentioned herbaria and relevant departments enabled work with specimens. Alexander N. Sen-nikov and Jin Danihelka are thanked for discussing certain taxonomic questions, as well as Alexander P. Shalimov for help with some literature. Research was supported by RFBF (project № 11-04-90702), DFG (project № KO 2302/13-1 "BrassiBase" within the Priority Program № 1529), and Ministry of Education and Science of Russia.
