Chromosome Numbers for Some Erodium L'Hér (Geraniaceae) Species of Iran
Erodium (Geranaiceae) species are distributed in different habitats of Iran. Some species are of medicinal importance while some are well known weeds. There are no chromosome counts for Erdoium species of Iran. Chromosome numbers are given for six taxa of Erodium (Geraniaceae) from Iran: E. cicutarium (2n=36), E. ciconium(2n=18), E. malacoides (2n=20), E. moschatum (2n=20), E. neuradifolium (2n...
متن کاملDiversity of chromosome numbers and meiotic studies in genus Anchusa (Boraginaceae) from Iran (10 Nov 2015)
The present study reports the chromosome number and meiotic behaviour of 14 populationsbelonging to four taxa of Anchusa subgenus Buglossum Gusul. from Iran. All populationsshowed the chromosome number 2n= 4x= 32. It is the first meiotic study for A. subg.Buglossum. We discuss some habit form and evolutionary aspect in the light of cytogeneticdata. The origin of polyploidy (auto-allopolyploidy)...

متن کاملAdditional Chromosome Numbers of American Acanthaceae
Original meiotic chromosome counts are presented for 39 species in 15 genera of Acanthaceae from Belize, Costa Rica, Ecuador, Mexico, Panama, the United States, and Venezuela. These reports include the first counts for 20 species representing 10 genera of the family, including the first chromosome number documented for the genus Poikilacanthus. Counts for 15 species confirm numbers previously r...
متن کاملCat’s Eyes and Popcorn Flowers: Phylogenetic Systematics of the Genus Cryptantha s. l. (Boraginaceae)
Cryptantha (Boraginaceae) is a group of approximately 200 annual and perennial species, representing two-thirds of the diversity within subtribe Cryptanthinae. The genus exhibits an amphitropic distribution, occurring in temperate and desert regions of western North and South America. Fifty samples of 45 species of Cryptantha s. l., exemplars of the related genera Amsinckia, Pectocarya, and Pla...
