Abstract:

A new genus of Compositae, Shangwua, is described to accomodate all species formerly placed in Saussurea sect. Jacea. This genus is distinct from the other genera of tribe Cardueae in its unique combination of states of characters including involucral bracts, receptacle, paleae, anther, style, achene and pappus. Phylogenetic analyses based on molecular data suggest that this new genus belongs to the Xeranthemum group, a lineage of the Carduinae that diversified early, with only distant relationships to Saussurea and related genera. The genus Shangwua consists of three species occurring in the Qinghai-Tibetan Plateau and Himalayas.
