Discussion | 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.) |
