This usually has been regarded as the same as O. Hookeri T. & 
G. The type of the latter came from California, that of the 
former from New Mexico. In the plant common in California 
and the Great Basin, the free tips of the sepals are about 4 mm. 
long, the pubescence of the leaves is short and that of the calyx 
not very copious. In the type of O. biennis hirsutissima and 
other specimens from New Mexico and Colorado, the free tips 
of the sepals are only 2-2.5 mm. long, the pubescence of the leaves 
and calyx long and loose, and that of the latter very copious.
