Subspecies 2 (2 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Euphorbia misera is relatively infrequent within the flora area, known primarily from coastal southern California and the Channel Islands (although a relictual inland population occurs in the Little San Bernardino Mountains). The species has been considered worthy of conservation, but appears to be under little threat, especially in Mexico where it is frequent and often locally abundant.
