In this survey, the chromosome counts of eight Nepeta L. species were investigated and karyotypic diversity among these was studied. The examined belong to N. cephalotes Boiss. group, namely eremokosmos Rech.f., gloeocephala Rech. f., Boiss., pungens (Bunge) Benth., ispahanica mahanensis Jamzad & Simonds, hormozganica denudata Benth. collected from different habitats in Iran. ploidy levels,...

Original meiotic or both and mitotic chromosome numbers are reported for ten endemic one non species in nine vascular plant families from Iran. The of Acantholimon schahrudicum, A. truncatum, Anthochlamys multinervis, Campanula perpusilla, Cousinia calcitrapa var. interrupta, Dorema ammoniacum, Euphorbia gedrosiaca, Hyocyamus orthocarpus were determined the first time. counts Astrodaucus persic...

Abstract In northern European Cochlearia (Brassicaceae), considerable chromosome variation has taken place without corresponding morphological differentiation, resulting in an intricate species complex including two base numbers and several ploidies. Here, we investigate the situation Iceland. The distribution, genetic structure, taxonomy origin of cytotypes (2n = 12 2n 14) present Iceland are ...

Previous chromosome information for the lower numbers 2n=14, 16, 18, and 20 in Asian Begonia are restricted to nine species two sections Diploclinium Platycentrum. Here we report first counts of four as well reconfirmed sect. We found 2n=12 B. cathcartii, lowest number known genus. The with reported is increased 13 Additionally, provide karyotypes seven Based on present results previous reports...

The karyology of five species Boesenbergia (B. collinsii, B. pulcherrima, rotunda, thorellii and xyphostachya) (Zingiberaceae) in Thailand are investigated. chromosome number karyotype formula the 2n=20 (8m+10sm+2st) 2n=36 (8m+18sm+10st) 2n=38 (18m+14sm+6st) (30m+8sm with one satellite) 2n=22 (6m+6sm+10st two satellites) xyphostachya, respectively. Three pulcherrima have new chromosomal counts....
