Abstract

Hymenoxys perpygmaea W. C. Holmes, Singhurst & Mink (Asteraceae, Helenieae, Tetraneuridinae) is described as a new annual species. The species, which is ephemeral, is endemic to an alfisol prairie that contains mima mounds in Lamar County from northeastern Texas, U.S.A. It is similar to H. texana (J. M. Coult. & Rose) Cockerell, but is easily distinguished from that species by its diminutive rosette and fewer florets per capitulum.
