Description |
Chromosome numbers for Eleocharis palustris subsp. palustris (based on 70 samples from Austria, Bulgaria, Croatia, the Czech Republic, Germany, Greece, Lithuania, Romania, Russia, Slovakia, Slovenia, and Sweden) and Eleocharis palustris subsp. vulgaris (based on 74 samples from Austria, the Czech Republic, Denmark, Germany, Ireland, Latvia, Luxembourg, the Netherlands, Portugal, and Sweden) are given. Also the chromosome number estimates based on relative DNA contents of plants from both subspecies from 8 localities E. palustris subsp. palustris from Croatia, the Czech Republic, Germany, Italy, Israel, and Slovenia, and from 18 localities of E. palustris subsp. vulgaris from the Czech Republic, Germany and Sweden are included. In E. palustris subsp. palustris 2n = 16 prevailed, the mixoploid 2n = 15, 16 was rare and a lone hypoploid 2n =15 was detected. In E. palustris subsp. vulgaris 2n = 38 was most frequently detected, the hyperploid 2n = 39 and mixoploid 2n = 38, 39 were common, rarer were the hypoploid 2n = 36 and mixoploids in which 2n ranges from 36 to 42. Distribution maps based on plants investigated either by chromosome counting or by flow cytometry, rounded out with karyologically documented literary data from earlier authors are given for both subspecies in Europe.
