Chorizanthe
''Chorizanthe'' is a genus of plants in the Polygonaceae, buckwheat family known generally as spineflowers. These are small, squat, herbaceous plants with spiny-looking inflorescences of flowers. The flowers may be in shades of red or yellow to white. The bracts are pointed and sometimes tipped with a hooked Awn (botany), awn, and the inflorescence often dries into a rounded, spiny husk. Spineflowers are found in western North America and South America. Name derivation: The word ''Chorizanthe'' comes from the Greek roots chorizo and anthos meaning "to divide," and "flower," thus meaning "divided flowers," but actually used in reference to the divided calyx.

''Chorizanthe rigida'', with the common names of devil's spineflower, rigid spineflower, spiny-herb, rigid spiny-herb, is an annual plant in the family Polygonaceae the buckwheats. It is a member of the genus ''Chorizanthe'', the spineflowers and is found in the southwestern United States and northwest Mexico, in the states of California, Nevada, Utah, Arizona, Baja California, and Sonora.
