متن کاملTaxonomic implications from morphological and anatomical studies in the section Stenodiptera from the genus Grammosciadium (Apiaceae)
Grammosciadium pterocarpum subsp. bilgilii and Grammosciadium pterocarpum subsp. sivasicum from Turkey are herein described as two new subspecies, and the species Grammosciadium schischkinii is synonymied under Grammosciadium pterocarpum subsp. pterocarpum. Quantitative variation of morphological and anatomical characters have been analysed to provide discriminative characters between the taxa ...
متن کاملMultiple origins promote the ecological amplitude of allopolyploid Aegilops (Poaceae).
Polyploidy has been ubiquitous in plant evolution and is thought to be an important engine of biodiversity that facilitates speciation, adaptation, and range expansion. Polyploid species can exhibit higher ecological tolerance than their progenitor species. For allotetraploid species, this higher tolerance is often attributed to the existence of heterosis resulting from entire genome duplicatio...

متن کاملTaxonomic 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...
