Morphology, Anatomy, Ecology, Pollen and Achene Structure of Centaurea consanguinea DC. (Sect. Acrolophus)

Abstract

Centaurea consanguinea DC is an endemic species belonging to the family Compositae (Asteraceae) Sect. Acrolophus. Morphology, anatomy, ecology, pollen and achene features of the species have been studied. C. consanguinea is a perennial species growing up 35-70 cm height. Leaf segments and involucral bracts are in different shape at the base and upper part. The root xylem and leaf mesophyll contain secretory canals. Spongy parenchyma in the leaf is highly reduced. The stem epidermis has papilla like ejections. The pollen is tricolporate. C. polyclada grows in the soil poor in calcium, medium in phosphorus and rich in organic matter content.
