Ilyinska Department of Systematics and Floristics of Vascular Plants, M. G. Kholodny Institute of Botany, National Academy of Sciences of Ukraine, Tereshszenkivska 2, 01601 Kiev, Ukraine, e-mail: ilantonina@yandex.ru Abstract: The key to the 14 species of Lepidium occurring in the Ukraine, including basionyms and the most important synonyms, and distribution of these species within the floristic regions, especially in Ukraine, are presented. 1. Introduction The Lepidium L. (Brassicaceae) genus comprises about 150-170 species widely distributed in temperate and subtropical regions, except the Far North and the Tropics, although it occurs in the mountains in the Tropics. The genus contains many taxonomically difficult species and infrageneric groups. Globally, the Lepidium genus was investigated only once, by Thellung (1906) but there were numerous regional studies of the genus. For example, Smirnov (1948) studied species endemic to chalks and limestone areas in Eastern Europe, while Dorofeev (2012) reconsidered this genus for Eastern Europe in general; De Carvalho & Vasconcellos (1964) studied all European species of the genus; Hewson (1982) dealt with Australian Lepidium. K. Latowski (1982) applied anatomical characters of fruits and seeds in the taxonomy of Lepidium; P. Wąsowicz and A. Rostański ( 2009) analyzed quantitative characters of three frequently misdiagnosed annual species (L. virginicum, L. ruderale L., L. densiflorum Schrad.). The Lepidium genus has been the subject of molecular studies for over 20 years. Molecular studies touched upon various taxa and focused on systematics (Mummenhoff et al. 2001), allopolyploidization events (Mummenhoff et al. 2004), evolution of flower structures (Bowman et al. 1999; Lee et al.2002), and development of dehiscent and indehiscent fruits (Mummenhoff et al. 2009) etc. In Ukraine, the cruciferous family, including the Lepidium genus, was investigated by Kotov (1953) who recorded 10 species of Lepidium (excl. Cardaria Desv.) in “Flora of the URSR” (excluding the Crimea). Kotov made the then most detailed treatment of the Lepidium genus (and other cruciferous) in Ukrainian flora. In his later publications, Kotov (1979, 1987) listed 12 species (added two Crimean species, L. tur­ czaninowii Lipsky and L. graminifolium L.) giving brief data concerning the distribution of all these species in Ukraine. Protopopova, Mosyakin and Shevera (1994) found in Transcarpathia and the Crimea new for the territory of Ukraine species – L. virginicum L. Later, in the LWKS herbarium, we found other specimens of this species, also collected in Transcarpathia: “Zakarpats’ka oblast, district Vynogradivs’ky, Eastern side of Koroleve settlement near railway and ‘поблизу’ quarry. 14.07.2006. Coll. О. Kagalo, О. Andreyeva, К. Doroshenko” (Ilyinska 2009). We presented L. pinnatifi­ dum Ledeb. as another new species for Ukraine based on herbarium specimens (deposited in LE!) which was redefined by K. Latowski (Ilyinska 2005). Leaf surface structure of four species of Lepidium and Cardaria were investigated by A. Ilyinska and M. Shevera (2004). Carrying out detailed taxonomic and floristic investigation of Lepidium in the flora of Ukraine, we selected lectotypes for two taxa: L. borysthenicum Kleopov and L. syvaschicum Kleopov (Ilyinska 2002). The results of taxonomic analysis of 13 species describing their morphological, biological and biomorphological characters, showing the current distribution of species in Ukraine (maps for each species applied) and reporting other features of species was presented in the fifth volume of “Ecoflora of Ukraine” (Ilyinska et al. 2007). ©Adam Mickiewicz University in Poznań (Poland), Department of Plant Taxonomy.

(Brassicaceae) in the flora of Ukraine The Lepidium genus is currently represented in Ukraine by 14 species. In this report, we summarize results of floristic investigation of Lepidium in the flora of Ukraine and provide the list of all species occurring in the country, including basionyms, the most important synonyms, nomenclatural types, and distribution of species within the floristic regions, especially in Ukraine, with the key to species. 2. Material and methods The study was based on herbarium material deposited in CWB, DNZ , JALT, KW, LE, LW, LWKS, LWS, MW (abbreviations following Index Herbariorum: http://sweetgum.nybg.org/ih/), original research results and literature data. 3.
