Karyological investigations of selected angiosperms from Georgia and Azerbaijan

Chromosome numbers of eleven angiosperm species, five dicots and six monocots from Georgia and Azerbaijan are reported. The chromosome number of Cruciata coronata (Rubiaceae) is provided for the first time (2n = 22). Additionally, karyotypes are presented for five species, those of Danae racemosa (Ruscaceae), Paris incompleta (Trilliaceae), and Ruscus hyrcanus (Ruscaceae) for the first time. The new data are compared with previous karyological information, and both are discussed in a biosystematic context.
