Achene Characteristics of Turkish Centaurea (asteraceae) and Their Systematic Application
This article investigates the exomorphic characteristics of the achenes which are achene size, color, and surface pattern, and pappus length, and colour. All these characteristics in seven taxa of Asteraceae namely, C. aggregata Fisch. & C.A. Mey. ex DC. subsp. aggregata, C. sivasica Wagenitz, C. polypodiifolia Boiss. var. polypodiifolia, C. polypodiifolia Boiss. var. szowitziana (Boiss.) Wagen...
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...

متن کاملTAXONOMIC REVISION OF THE CYPERUS SUBGENUS CYPERUS IN IRAN
The genus Cyperus belongs to tribe Cypereae, subfamily Cyperoideae and family Cyperaceae that is the largest genus in this family after Carex. The classification of genus Cyperus is still unsettled because of morphological variations and therefore, makes determination of subgenera boundaries and species difficult. In Flora Iranica (KUKKONEN 1998) this genus was divided to six subgenera. In this...
