Discussion

Castilleja cusickii includes two morphologically distinct variants. One variant has a wider inflorescence, broader bracts, and wider bract lobes. These bracts often have highly contrasting purple veins, and some populations also have a purplish wash on the bracts. These plants have a range on the western edge of typical C. cusickii, though overlapping with more typical forms in western Idaho and adjacent northeastern Oregon and southeastern Washington. The name C. lutea is available for these variants, and both consistent morphological differences and preliminary results from ongoing genetic research on the plants (D. C. Tank, pers. comm.) indicate its resurrection may be justified. A second variant is distinguished by a pale pink-purple wash on the bracts and a narrow distribution in the meadows of the Bear River Valley, bordering northwestern Utah and adjacent southeastern Idaho. Only bract coloration appears to distinguish this form from typical C. cusickii, and the distinctive bract coloration is only more or less consistent in these populations.

Typical Castilleja cusickii appears to hybridize with C. gracillima in the Logan Valley, Grant County, Oregon. It is also reported by M. Ownbey (1959) to hybridize with C. miniata and C. rhexiifolia.

Castilleja chrymactis is restricted to the coast of southeastern Alaska, from Glacier Bay to Yakutat. In some respects, it resembles a hybrid swarm between C. miniata and C. unalaschcensis. If C. chrymactis originated as a hybrid, at present it has formed a number of populations and has a stable morphology that differs from both putative parents, especially in calyx structure. Reports of its introduction to Point Reyes, California (T. I. Chuang and L. R. Heckard 1993b), are based on C. leschkeana, a distinctive species known only from two records near the type locality and presumed to be extinct.
