Discussion | Castilleja viscidula is a member of the complex including C. applegatei and C. martini, centered in California. Castilleja viscidula favors isolated mountain ranges, from the Wallowa and, possibly, the Blue mountains of northeastern Oregon, eastward into southwestern Idaho, and southward into central Nevada. Most populations are greenish yellow, but in one portion of the Wallowa Mountains, reddish bracted plants are common. Many yellowish bracted populations in the same mountain range surround this reddish population. Intermediate color forms are rarely encountered. Most ranges where C. viscidula occurs have generated slightly differing local races, demonstrating some reproductive isolation and divergence. In addition, hybrid swarms between this species and C. nana are known from several mountain ranges in central and northern Nevada, and an apparent hybrid with C. flava var. flava is known from the Independence Mountains of northern Nevada.

Varieties 4 (4 in the flora). Castilleja ambigua is a complex species, treated here with four varieties, though many localized variations exist among populations, and these are still incompletely understood. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
