Discussion | Castilleja cryptantha is endemic to the vicinity of Mt. Rainier in the Cascade Range, with most populations found within Mt. Rainier National Park. Unlike most species of Castilleja, it is apparently self-pollinating (W. J. Duffield 1972); the small flowers are entirely enclosed within the yellowish calyces, which tend to grow deep reddish as they age. The purplish brown bracts are also unusual in the genus.

Varieties 3 (3 in the flora). Castilleja pilosa is a widespread and variable complex similar in growth form and coloration to C. pallescens and related species. However, C. pilosa is distinguished with relative ease by its subequally divided calyces. Plants of the C. pallescens complex have very shallow lateral calyx lobes.
