Discussion | Erythranthe patula is distinctive with its long-petiolate leaves with ovate blades and its small, weakly bilabiate to nearly radially symmetric corollas. Vestiture may include only minute, stipitate-glandular hairs or it may be an intergrading mix of stipitate-glandular hairs and minute (0.1–0.2 mm), sharp-pointed, eglandular hairs. Plants may have stipitate-glandular pedicels and calyces but hirtellous, eglandular stems, or they may have stipitate-glandular stems and pedicels but hirtellous calyces.

Erythranthe trinitiensis is similar to E. pulsiferae in its narrow leaves, glandular-puberulent vestiture, and weakly bilabiate corollas; it differs in its early-shed basal leaves, cauline leaves with one-veined petioles, and yellow corolla tubes and throats with pink lobes or lobe margins. The species is known only in Humboldt, Siskiyou, and Trinity counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
