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.

Castilleja gracillima populations are centered around the Greater Yellowstone region, but its range extends sporadically west to central Oregon. It is sometimes confused with C. miniata, but differs from that species in its floral dimensions, mostly single-stemmed growth form, primarily white, yellow, or pinkish orange bract coloration, puberulent stems, and weakly rhizomatous habit. Where the two grow in the same general region, there is no clear evidence of hybridization; however, C. cusickii and C. gracillima form an extensive, sporadically intergrading population in the Logan Valley, Grant County, Oregon.

Plants attributed to this species from the Rocky Mountain trench near the head of the Columbia River in southeastern British Columbia or adjacent Alberta are a combination of several other species, especially Castilleja lutescens and C. miniata.
