TAXONOMIC 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...

A TAXONOMIC REVISION OF THE GENERA STERIGMOSTEMUM AND PETINIOTIA IN IRAN

The genus Sterigmostemum M. Bieb. belongs to the tribe Hesperideae of the Brassicaceae family. The results of this research confirmed the recognition of five species in Iran: S.incanum, S. sulphureum,  S. ramosissimum,  S. acanthocarpum  and S. longistylum. S. laevicaule is excluded from the genus Sterigmostemum and is regarded as a synonym of Erysimum crassicaule. The new combination, namely, ...

A revision of Gonolobus s.s. (Apocynaceae: Asclepiadoideae: Gonolobinae) in the West Indies is provided based on recent evidence of support for the monophyly of the genus from molecular and morphological data. Ten species are recognized (eight endemic to a single island each). Keys, descriptions, and illustrations are provided for all ten species. The conservation status of each species is prov...
