Jacobaea borysthenica (DC.) B. Nord. & Greuter in Willdenowia 36: 712. 2006.

≡ Senecio praealtus var. borysthenicus DC., Prodr. 6: 351. 1838. ≡ Senecio borysthenicus (DC.) Andrz. ex Czern., Consp. Pl. Charcov. : 32. 1859. ≡ Senecio jacobaea var. borysthenicus (DC.) Trautv. in Bull. Cl. Phys.-Math. Acad. Imp. Sci. Saint-Pétersbourg 12: 351. 1854.

Lectotypus (designated here): UKRAINE. Reg. Mykolayiv: “circa Kislakowka gub. Cherson. 29.” [Vitovs’ky Distr., Lymany], s.d., Anon. [Andrzejowski] s.n. ( G-DC [G00471753] !) . Syntypi: UKRAINE. Reg. Mykolayiv: “ Kislakowka. Gub. Cherson ”, s.d., Anon. [Andrzejowski] s.n. ( G-DC [G00471752] !). Reg. unknown: “E pratis Pod[oliae]. austr.”, s.d., Anon. [Andrzejowski/Besser] s.n. ( G-DC [G00471754] !) ( Fig. 1 ) .

Notes. – We designate the specimen G00471753 as lectotype as it is the most complete material and bears the most complete locality information precisely identifying the collection site as Lymany, formerly Kyslyakivka village, transliterated by ANDRZEJOWSKI (1823: 23) in Polish as “Kiślakówka”. Furthermore, it bears the annotation “ Senecio borysthenicus Andrz. ” in Besser’s handwriting. The syntypes bear two other determinations: “ Senecio affinis tenuifolio borysthenico” [G00471752] and “ Senecio tenuifolius ? involucri squamis enerv. ciliatis apice spha[…]” [G00471754].

Each original specimen in G-DC bears a blue label with words “Herb. W. Besser” typographically printed in the bottom right corner ( Fig. 1 ). This blue paper is identical to the one used for publication of the first edition of Besser’s Catalogue ( BESSER, 1810). The number “29” on the label of the lectotype has a stroke above, meaning 1829; that was Besser’s usual manner of indicating the year of collection or provenance. In that case it is the year of provenance by Besser and not the actual collection year, because Andrzejowski (who was the actual collector, based on historical data; see ANDRZEJOWSKI, 1823, 1830) visited the area not in 1829 but earlier, in the 1810s and early 1820s but not later than 1824.

The geographic location of the specimen G00471754 is uncertain because the label data indicating Southern Podolia may refer to any area in the southern part of the former Podolian Governorate, now partly in Khmelnytskyi (south), Vinnytsya (south), Odesa (north), and Mykolayiv (west) regions of Ukraine.

The authorship of the recombination Senecio borysthenicus was sometimes attributed to Leopold F. Gruner ( GRUNER, 1869: 423), Sergei S. Stankov (STANKOV & TALIEV, 1949: 651; see CHATER & WALTERS, 1976), or to Boris K. Schischkin (SCHISCHKIN, 1961: 718). In fact, the species-rank combination was validated by Vasiliy M. Czerniaëw (also sometimes Romanized as Basilius Czernajew) ( CZERNIAËW, 1859: 32), who cited this species under Senecio as “748. Borysthenicus. Andrz. Ch. [Charkovia – Kharkiv]. In arenosis”. Czerniaëw partly misapplied that name to East Ukrainian specimens of Jacobaea vulgaris and (probably) J. andrzejowskyi (Tzvelev) B. Nord. & Greuter as it is evident from his herbarium specimens at KW. The authorship of the combination Senecio jacobaea var. borysthenicus was occasionally attributed in literature to Ivan Fedorovich (Johannes Theodor) Schmalhausen (SCHMALHAUSEN, 1886) or L.F. Gruner ( GRUNER, 1869). However, this combination (as “ borysthenica ”) was validated already in 1854 by Ernst R. von Trautvetter (TRAUTVETTER, 1854: 351; see also TRAUTVETTER, 1855: 131), with the direct reference to the basionym and to the unpublished species-rank name proposed by Andrzejowski.
