Discussion | The densely, evenly puberulent vestiture of pedicels, calyces, and distal stems usually is diagnostic, especially in combination with the large flowers (corollas and mature calyces) and tall stature. Plants from scattered collections are much shorter than normal but have large corollas and characteristic vestiture. Erythranthe grandis characteristically occurs in coastal localities from southern California to northern Oregon but also is found in inland localities and habitats near the coast but well away from salt spray.

Erythranthe regni is endemic to the Kofa Mountains of Yuma County; all collections have been made from the Kofa Game Refuge (Kofa National Wildlife Refuge). Because its calyces remain open at maturity, this species is hypothesized to be most closely related to E. geyeri, from which it differs by its erect habit, apparently annual duration, larger leaves, purple-dotted calyces, and corollas with longer tube-throat and barely bilabiate limb. Geography and other morphology, however, suggest that its evolutionary origins are closer to E. guttata. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
