Chromosome numbers for some species of the flora of Dagestan

We investigated the chromosome numbers (2n) of 18 plant species (22 populations) from the families Alliaceae, Amaranthaceae, Apocynaceae, Asteraceae, Brassicaceae, Boraginaceae, and Caryophillaceae sampled in Dagestan. The following nine species were studied for the first time in Russia and hence in Dagestan: Heliotropium suaveolens M. Bieb. (2n = 32, tetraploid cytotype), Allium rubellum M. Bieb. (2n = 24, triploid cytotypes), diploids Atriplex aucheri Moq. (2n = 18), Cynanchum acutum L. (2n = 22), Crepis alpina L. (2n = 10), Crepis marschallii (C. A. Mey.) F. Schultz (2n = 8), Crepis pulchra L. (2n = 8), Crepis sancta (L.) Bornm. (2n = 10), Hedypnois cretica (L.) Dum.-Cours. (2n = 12), and Gypsophila scorzonerifolia Ser. (2n = 34). New data for Dagestan are reported for Crupina vulgaris (Pers.) Cass. (2n = 30), Picris strigosa subsp. canescens (Steven) Lack (2n = 10), Xanthium orientale var. albinum (Widder) Adema et M. T. Jansen (2n = 36). New cytotypes were first to be found in the territory of Russia: triploid cytotype in Alyssum desertorum Stapf (2n = 3x = 24) and diploid cytotype in Alyssum alyssoides (L.) L. (2n = 16). Each species is provided with distribution area and published data on chromosome numbers.
