Taxonomic significance of achene morphology in the genus Centaurea L. (Asteraceae)
Achene morphology of 49 taxa of the genus Centaurea L. was studied in terms of 19 different characteristics. On the basis of the variation in these features, some sections, such as sect. Cyanus with hairy hilum, were separated. Despite various differences, C. leuzeoides and C. gilanica were categorized in the section Psephelloideae, a section with lots of character variations within its species...
متن کاملMICROMORPHOLOGY OF SEED IN SOME VICIA SPECIES FROM IRAN

The main pattern in seed coat sculpturing in the species was papillose, but the size and the number of side ribs in papillae and the density of papillae, were different in various species. Four morphological characters of seeds: relative hilum length and shape, relative position of th...
متن کاملStructure of the Pericarp in Some Amaranthus L. (Amaranthaceae) Species and Its Taxonomic Significance
In order to determine their taxonomic significance, 10 pericarp structure characters were scored for 21 Amaranthus L. taxa. In many, peri carp patterns permit recognition of the taxa as species. Differences between cultivated taxa and their wild relatives offer new arguments against their taxonomic union. The relationships between other closely related taxa are also analyzed (A. quitensis and A...
