Information on the occurrence of Bupleurum baldense in the W Balkan Peninsula ( Hand 2011 +; GBIF 2021a) needs to be confirmed and probably refers to B. veronense or other taxa. In Crimea, B. baldense was collected for the first time by L. V. Bondareva in the spring of 2000 on the N slope of Mount Sapun and in 2001 in the Yukharin ravine. However, the specimens were incorrectly identified by her as B. odontites L. ( Bondareva 2013; https://www.gbif.org/occurrence/3464982509; https://www.gbif.org/occurrence/3464983447), because exactly this similar species was previously indicated for the surroundings of Sevastopol ( Vinogradova 1979). Later, these findings were confirmed by photographs by P. E. Yevseyenkov and S. A. Svirin on the Plantarium (2007 –2022) website, but these photos were also misidentified, this time as B. veronense . Under the latter name, the species was included in the flora of the Sevastopol region and Crimea as a native plant ( Seregin & al. 2015; POWO 2022c). One of the photos was correctly identified by S. Stoyanov as B. baldense . On this basis, Seregin & al. (2015) adduced the only location of B. baldense in Sevastopol, and the status of the species was designated as alien, probably naturalized. Further study showed that all plants from the vicinity of Sevastopol, previously identified as B. veronense , actually belong to B. baldense . At least four local populations of this species are now known in the region ( GBIF 2021a), with numbers ranging from several hundred to several thousand individuals each. Given the significant disjunction of the range and the distribution pattern of B. baldense in the vicinity of Sevastopol, it can be assumed that this species is not a native plant there, but was introduced from the Mediterranean with forage during the Crimean War of 1853–1856. Now B. baldense has become one of the dominant elements of the rocky, calciphilous steppes of the Heracleian peninsula of SW Crimea and is completely naturalized there. L. E. Ryff, L. V.
