tailieunhanh - Allium cyrilli complex (sect. Melanocrommyum) in Turkey

As a part of a revisional study of the genus Allium L. sect Melanocrommyum Webb et Berthel. in Turkey, detailed studies were conducted on 3 very closely related and taxonomically difficult species cited in the Flora of Turkey: Allium cyrilli Ten., A. atropurpureum Waldst. & Kit., and A. decipiens Fisch. ex Schult. & Schult. f., to clarify their occurrence in Turkey and their taxonomy. | Turkish Journal of Botany Research Article Turk J Bot (2013) 37: 39-45 © TÜBİTAK doi: Allium cyrilli complex (sect.

The results of this study show that A. atropurpureum and A. decipiens do not occur in Turkey. On the other hand, A. cyrilli is represented by 3 subspecies of which 2 are new for science: subsp. fritschii & and subsp. asumaniae & . The diagnostic morphological characters, distribution, conservation status, and colour photographs of the 3 subspecies as well as their chromosome numbers are presented: 2n = 16 (diploid) for subsp. fritschii, and 2n = 32 (tetraploid) for subsp. asumaniae and subsp. cyrilli. Key words: Allium, Melanocrommyum, chromosome number, new subspecies, Turkey 1. Introduction The genus Allium L. is a very variable and taxonomically difficult genus naturally distributed over the northern hemisphere. The most recent classification proposal for this genus based on morphological characters and considering also molecular data accepted about 780 species belonging to 15 subgenera (Friesen et al., 2006). Recent additions raised the species number to more than 850 (Keusgen et al., 2011). The taxonomic classification of the genus Allium is still in progress. The subg. Melanocrommyum (Webb et .
