Chromosome counts of some Alchemilla species from series Calycinae

This paper presents the results of karyological analysis of four species fr om the section Alchemilla ROTHM., subsection Calycantum ROTHM., series Caly cinae Bus. Specimens studied karyologically originated from Northeast Anato lia (Turkey). Their chromosome numbers were as follows: A. transcaucasica R OTHM. 2n = 128 - 140; A. retinervis Bus. 2n = 101 - 106; A. ellenbergiana R OTHM. 2n = 120 - 132; A. dura Bus. 2n = 108 - 126. From cytological point o f view Alchemilla represents a difficult object. All studied species from N ortheast Anatolia are proven to be high polyploids like species of Alchemil la investigated from various geographic areas.
