Discussion

Castilleja rupicola is usually found in the subalpine and lower alpine zones in the Cascade Range from extreme southern British Columbia south to northern Douglas County, Oregon. Though it can be numerous where it occurs, the species as a whole is uncommon. One atypical population occurs in a moist, shaded, mossy, north-facing ravine on the Oregon side of the Columbia River Gorge, at less than 250 m. These plants often bear secondary divisions on deeply dissected leaves and bracts.

Castilleja dissitiflora is endemic to several mountain ranges in central and eastern Nevada, in the upper montane and lower subalpine zones. It has the deep abaxial calyx cleft of C. linariifolia and the stipitate-glandular, wavy-margined leaves of C. applegatei var. pinetorum. Based on morphological data, Holmgren suggested that it is an allopolyploid derived from hybridization of C. applegatei var. pinetorum and C. linariifolia. His proposal is plausible and should be further tested. Castilleja dissitiflora is a tetraploid, while both putative parental species have at least some diploid populations.
