MOSYAKIN, S.L., N.M. SHIYAN & I. HODÁLOVÁ (2019). Lectotypification of Senecio praealtus var. borysthenicus (Asteraceae). In English, English abstract. Candollea 74: 217–221.

Senecio praealtus var. borysthenicus DC. (Asteraceae) was described based on specimens from Ukraine provided by Wilibald S.J.G. von Besser (1784–1842) and annotated by Antoni L. Andrzejowski (1785–1868) as “Senecio borysthenicus”. This taxon was previously recognized as Senecio borysthenicus (DC.) Andrz. ex Czern. and is currently accepted as Jacobaea borysthenica (DC.) B. Nord. & Greuter. A lectotype is designated for this name based on a specimen collected near the village of Kyslyakivka, Kherson Governorate (now Lymany, Mykolayiv Region, Ukraine), one of three original specimens studied by Augustin-Pyramus de Candolle (1778–1841) and deposited in G-DC. The authorship of Senecio borysthenicus and Senecio jacobaea var. borysthenicus is also discussed.
