Jump to: navigation, search


Lygodesmia is easily recognized by the green, rushlike stems, narrow and often greatly reduced leaves, and terminal heads of showy, rosy, ligulate florets. It has been consideredcongeneric with Stephanomeria, Prenanthella, and Shinnersoseris; A. S. Tomb (1980) concluded that those taxa are not closely related. The annual species with plumose pappus bristles that formerly were included in Lygodesmia have been removed to those genera.
