Discussion | Castilleja cervina is found across northern Washington, from the eastern slope of the Cascade Range, east to northern Idaho and north to southern British Columbia. Plants at higher elevations are dwarfed. Reports from Montana need verification. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
