Discussion
Species 48 (9 in the flora).
Drymaria arenarioides Willdenow ex Schultes, alfombrilla, is on the Federal Noxious Weed List. It is highly toxic to livestock and is native in northwestern Mexico, where it has been reported within a few miles of the United States border.
J. A. Duke (1961) proposed an infraspecific classification for Drymaria consisting of 17 “informal” series that he did not validly publish. Some of Duke’s series were cited by M. Escamilla and V. Sosa (2000), apparently assuming that they were “real” series.
