LEIBNITZIA

Jump to: navigation, search


Two species of Leibnitzia occur in North America (one is restricted to western Mexico); the remaining four are Asian. The species are characterized by dimorphic heads: those produced in the spring appear before or with the leaves and are chasmogamous and quasi-radiate; the fall forms appear after the leaves and are cleistogamous (not exposing any florets but setting full fruit). The florets also differ morphologically between the chasmogamous and cleistogamous heads. The widespread American species (L. lyrata) has been placed within Chaptalia; species of Leibnitzia are distinguished from all Chaptalia species by the slender, sharp-pointed hairs on their cypselae.
