Discussion

Castilleja litoralis never ranges more than one to two kilometers from the sea, from Humboldt County, California, north to Pacific County, Washington, near the mouth of the Columbia River. It is a high polyploid complex, possibly incorporating the genomes of several species, including C. affinis, C. miniata, and possibly C. hispida. The coastal C. miniata var. dixonii is very similar ecologically and morphologically but replaces C. litoralis from southwestern Washington to southern British Columbia. Compared to C. litoralis, C. miniata var. dixonii usually has somewhat longer corollas and corolla beaks, the latter with a more conspicuously puberulent surface and deeper lateral calyx clefts. Castilleja litoralis has been included as a subspecies of C. affinis by some (for example, M. Wetherwax et al. 2012), but the morphological resemblance to that species is far more tenuous than it is to C. miniata var. dixonii. Considering their very similar morphologies, along with the fact that both C. litoralis (2n = 120, 144) and C. miniata var. dixonii (2n = 96, 144) apparently combine multiple genomes, strongly suggest that they would best be treated as a single entity. Should they be combined at the species level following additional research, the name C. dixonii has priority.

Castilleja litoralis is often associated with salal, Gaultheria shallon, on which it is likely parasitic.

Castilleja linariifolia is widespread in the western United States and is important to Native Americans as a source of dyes and for medicinal and ceremonial purposes (D. E. Moerman 1998). It is the state flower of Wyoming. Castilleja linariifolia is closely associated with, and undoubtedly parasitic on, the roots of sagebrush, Artemisia tridentata. The bracts are usually red to red-orange, with uncommon yellow-bracted variants. On the eastern slope of the Sierra Nevada in California, most populations have pink-purple to magenta bracts, and at least one population has almost pure white bracts. Plants associated with hot springs in the Ash Meadows area of Nye County, Nevada, are unusually tall and have somewhat fleshy leaves. Castilleja linariifolia stems are usually glabrous, but pubescent stems are sporadic across its range. However, in the Mt. Charleston area of the Spring Mountains, in southern Nevada, most plants are pubescent, ranging from an inconspicuous layer to a fairly dense and obvious indument. These plants have been called forma omnipubescens Pennell. Elsewhere, especially in central and northern Arizona, individuals with short-pubescent stems are intermingled with more typical plants. In addition, late-blooming forms associated with hot spring sites in the eastern Mojave Desert are particularly thick-stemmed and vigorous. Hybrids between C. linariifolia and C. scabrida are known from Garfield County, Utah. Castilleja linariifolia is parapatric with the similar C. wootonii in central New Mexico. Castilleja linariifolia is reported to hybridize with C. chromosa, C. flava, and C. miniata. A possible hybrid with C. septentrionalis was named C. ×cognata Greene.
