Discussion | The range of Erythranthe eastwoodiae appears to be essentially contiguous with that of E. verbenacea in the Grand Canyon region, but there is no evidence of hybridization. Erythranthe eastwoodiae (as Mimulus eastwoodiae) is in the Center for Plant Conservation’s National Collection of Endangered Plants.

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.) |
