Spineflower
''Chorizanthe'' is a genus of plants in the 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, 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. Selected species: * '' Chorizanthe angustifolia'' - narrowleaf spineflower * '' Chorizanthe biloba'' - twolobe spineflower * '' Chorizanthe blakleyi'' - Blakley's spineflower * '' Chorizanthe brevicornu'' - brittle spineflower * '' Chorizanthe breweri'' - San Luis Obispo spineflower * ''Chorizanthe corrugata'' - wrinkled spineflower * ''Chorizanthe cusp ...

Chorizanthe Rigida
''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. Distribution ''Chorizanthe rigida'' is a common desert plant found in the Sonoran and Mojave Desert - in bajadas (washes), flat mesas that flood with annual rains, and rocky hillsides and ridgelines. A locale range example is its presence in most habitats of the Muggins Mountains Wilderness in southeastern Arizona. In desert flats, the short 3 inch plant can be easily obscured, by downstream-washed debris that easily collects on the ''spineflower'' skeleton. Thus small hillocks of debris are found, a spineflower in the core; possibly this is the advantageous form of germinating at least the s ...
