21b. Senecio racemosus subsp. kirghisicus (Candolle) Calvo in Calvo et al. (2014: 141). Cineraria glabrata Ledebour (1829 : tab. 94), nom. illeg. ( McNeill et al. 2012, ICN Art. 53.1), replaced name, non Swartz (1806: 1354). Senecio kirghisicus Candolle (1838a: 362) , replacement name, non Senecio glabratus Hooker & Arnott (1830: 32) . Senecio doria subsp. kirghisicus (Candolle) Chater in Heywood (1974: 276). Jacobaea kirghisica (Candolle) Wiebe (2000: 62) . TYPE: Kazakhstan, [Kara-su stream according ind. loc.], C.F. Ledebour s.n. (lectotype, designated by Calvo et al. (2014: 141), LE!).

Synflorescence racemose or narrowly paniculate. Achenes with trichomes along ribs. Chromosome number: unknown. Figure 27 .

Iconography: — Ledebour (1829: 22, tab. 94, sub C. glabrata ); Wissjulina (1962: 376, fig. 71, sub S. paucifolius ); Konechnaya (1994: 61, pl. 5, fig. 1, sub S. paucifolius ).

Distribution and habitat: — Kazakhstan, Ukraine, Russia; meadows, steppes, on solonchak and solonetz soils; elevations of 20–700 m ( Figure 29 ).

Phenology: — Flowering from June to September.

Discussion: — The epithet kirghisicus refers to the “deserti Kirghisorum ” ( Kazakhstan), cited in the protologue of Cineraria glabrata by Ledebour, and subsequently repeated by Candolle in the protologue of S. kirghisicus . For details on the lectotypification of C. glabrata and nomenclatural explanation see Calvo et al. (2014).

The populations of S. racemosus subsp. kirghisicus represent the eastern limit of the Crociseris distribution, at eastern Kazakhstan.
