Polyarrhena
''Polyarrhena'' is a genus of low, branching shrublets that is assigned to the Asteraceae, daisy family (Compositae or Asteraceae). Its stems are alternately and densely set with entire or somewhat toothed leaves. Like in almost all Asteraceae, the individual flowers are Merosity, 5-merous, small and clustered in typical heads, and which are surrounded by an involucre of in this case three whorls of bracts. In ''Polyarrhena'', the centre of the head is taken by yellow Asteraceae#Floral heads, disc florets, and is surrounded by one single whorl of white Asteraceae#Floral heads, ligulate florets that have a pinkish-purple wash on the underside. These florets sit on a common base (or Receptacle (botany), receptacle) and are not individually subtended by a bract (or palea). The species occur in the Cape Floristic Region. ''Polyarrhena reflexa'' has long been cultivated as an Ornamental plant, ornamental and is often known under its synonym ''Aster reflexum''. Taxonomy In his famous ...
