Discussion	Erythranthe norrisii is known only from the Kaweah River drainage; most populations are in Sequoia National Park in Tulare County. The species is characterized by its short-petiolate leaves with attenuate bases, very large corollas with red splotches at the base of each lobe and two white patches on the abaxial limb, and very short, purple-dotted calyces with rounded-thickened ribs and linear-oblong lobes incurved in fruit. The capsules often are slightly exserted. (Discussion copyrighted by Flora of North America; reprinted with permission.)	Erythranthe inamoena is distinctive in its completely glabrous herbage, small corollas, flowers in racemes mostly at distal nodes and with reduced bracts, short and open-throated fruiting calyces, erect and fistulose stems, and apparent annual duration (fibrous-rooted but usually rooting at proximal cauline nodes). Presumably because of its autogamous reproduction, Erythranthe inamoena has been confused with E. cordata, especially in the trans-Pecos region of Texas, where the two are sympatric. In contrast to E. cordata, E. inamoena usually has glabrous pedicels and calyces, flowers often produced from all nodes, smaller calyces [(7–)8–11 mm] that do not close at maturity, and corollas with a shorter tube-throat (7–11 mm). Some populations in Brewster, Presidio, and Val Verde counties are identified here as Erythranthe inamoena (based on proximal-to-distal distribution of flowers and the short mature calyces with open throat) but have sparsely stipitate-glandular pedicels and calyces.
