Discussion | Varieties 4 (4 in the flora). Castilleja miniata is widely recognized as the common scarlet paintbrush. It is highly variable and has five levels of polyploidy. Nonetheless, it remains fairly well defined morphologically across its wide range. Native Americans use it medicinally. A probable hybrid with C. septentrionalis from southern Nevada was named C. ×porterae Cockerell. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Castilleja wightii is found along or near the central and northern coast of California. Historical collections of C. wightii from Curry County, Oregon, are referable to other species, but it should be sought in the area. Reports from the south-central coast of California are referable to other species, particularly C. affinis. Castilleja wightii appears to intergrade with C. latifolia and perhaps C. affinis south of San Francisco. Despite much attention from botanists, the perennial paintbrushes along the coast between Monterey and San Francisco can be perplexing and difficult to identify. This situation is likely the result of introgression, but this complex is in need of meticulous genetic and morphological analysis. North of San Francisco, C. wightii is straightforward to recognize, with its abundantly stipitate-glandular stems and leaves. In addition, the leaves are often crowded on the stems, which bear axillary shoots. Most populations have either red or yellow bracts, with only occasional individual plants of the other color. Yellow populations are found primarily in Marin and southern Sonoma counties southward and are gradually replaced by red populations from northern Sonoma County northward. Mixed color populations occur in a few places, especially in San Mateo County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
