The chromosome numbers and karyotypes of eight species of the genus Muscari distributed in Turkey were analyzed. These taxa are M. macrocarpum Sweet, M. racemosum Mill., M. aucheri (Boiss.) Baker, M. armeniacum Leichtlin ex Baker, M. sivrihisardaghlarensis Yıldırımlı & B. Selvi, M. discolor Boiss. & Hausskn, M. botryoides (L.) Mill. and M. neglectum Guss. Five of them (M. racemosum, M. aucheri, M. sivrihisardaghlarensis, M. discolor, and M. botryoides) are endemic in Turkey. The chromosome number of all studied taxa were determined as 2n=2x=18, while M. neglectum had the chromosome number of 2n=4x= 36. Haploid chromosome lengths varied 24.94 µm (M. armeniacum) to 119.85 µm (M. racemosum) among species. Karyotype analysis indicated that Muscari taxa generally have a median point (M), median (m), and submedian (sm) chromosomes. In addition, only M. racemosum has one subterminal (st) chromosome pair. Satellites were observed in M. racemosum and M. botryoides. The karyotypes of M. sivrihisardaghlarensis was determined for the first time in this study.

The chromosome numbers and karyotypes of 11 species the subgenus Leopoldia of the genus Muscari distributed in Turkey were analyzed. These taxa are M. comosum (L.

Bellevalia behcetii (Asparagaceae) is described and illustrated as a new species from Şırnak province in South Eastern Anatolia (Turkey). It is morphologically similar to B. paradoxa but easily differs in several morphological characters. Diagnostic morphological characters, a full description and detailed illustrations of the new species are provided. A quantitative morphometric analysis was carried out to check the diagnostic characters of Bellevalia behcetii with respect to morphologically related species. The somatic chromosome number was determined as 2n = 2x = 8 in B. behcetii. In addition, the ecology and phenology of the new species, as well as its etymology and the pollen characteristics, are presented and discussed. The conservation status of B. behcetii was assessed according to IUCN protocol. A distribution map of B. behcetii and related species is also presented.

The taxonomical status of Muscari haradjianii from Turkey was reevaluated in this study. We provide here a detailed morphological description, including pollen and seed features, distribution range, and chromosome number. There has been frequent confusion regarding the differences between M. haradjianii and its congeners M. longipes and M. tenuiflorum. Here, we clarify the differences among these species. In addition, it was determined that M. ufukii is a synonym for M. haradjianii.
