Rosularia sempervivoides

Rosularia is a small genus of the family Crassulaceae. It includes about 28-35 species from Europe, the Himalayas, and northern Africa.

Taxonomy

Rosularia was originally described by De Candolle (1828) as a section of the genus Umbilicus,Template:Sfn and raised to the level of genus by Stapf (1923)Template:Sfn Thus the genus bears the botanical authority (DC) Stapf of both authors.Template:Sfn

In 1930, Berger included it in family Crassulaceae subfamily Sedoideae, as one of 9 genera.Template:SfnTemplate:Sfn He further divided it into two sections (Eu-Rosularia and Ornithogalopsis) and further series,Template:Sfn transferring some species of Sedum to it. Since then, a number of species have been transferred in and out of the genus, including S. sempervivoides, which at one stage was placed in Prometheum.Template:Sfn The genus Sempervivella was submerged in Rosularia.Template:Sfn The genus is now placed within the Leucosedum clade, tribe Sedeae, subfamily Sempervivoideae of the Crassulaceae, but is embedded within Sedum paraphyletically.Template:SfnTemplate:SfnTemplate:Sfn

Distribution and habitat

Rosularia is found in arid and semi-arid regions from North Africa (Morocco, Ethiopia), through the eastern Mediterranean to Central Asia (north of Tien Shan and east of W Himalaya), including Pakistan.Template:SfnTemplate:Sfn

Ecology
