This usually has been regarded as the same as 0. 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 0. 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.
