Dianthoveus: A New Genus of Cyclanthaceae

Abstract

Dianthoveus cremnophilus, aterrestrial Cyclanthaceae from southwestern Colombia to northern Ecuador, is described as a new genus and species.The cupules at the base of the stamens and the long, narrow, moderately flattened seeds are unique.Cladistic analysis supports the hypothesis that leaf idioblasts with randomly oriented styloids (leaves scabrous when dry), root styloids, sessile anthers, and inaperturate pollen are synapomorphies with the
