TWO NEW SPECIES OF ERYTHRANTHE SECT. MIMULOSMA (PHRYMACEAE)

Erythranthe trinitiensis Nesom, sp. nov. , is endemic essentially to the Trinity Alps of northwestern California (Humboldt, Siskyou, and Trinity cos .). It has been identified as E. pulsiferae but differs most consistently in corolla color and in ha ving inflated calyces. The two species apparently are closely sympatric at least in some areas. Erythranthe taylori Nesom, sp. nov. , apparently is narrowly endemic to limestone habitats in nor thwestern Shasta County. It is distinctive in its petiolate leaves with ovate blades, strongly herkoga mous flowers with distinctly 2-lipped corollas, and papillose calyx vestiture.
