Corollas

yellow, base of each lobe with a prominent maroon splotch, abaxial limb with white patch at 2 sinus bases, weakly bilaterally or radially symmetric, weakly bilabiate or regular;

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.

In the protologue, R. J. Meinke observed that plants of Erythranthe hymenophylla have reflexed fruiting pedicels that increase seed dispersal back onto the vertical cliff wall, the characteristic habitat of the species. The hanging habit of E. hymenophylla is reflected in a sharp (90º to 180º) bend in the basal nodes and the long pedicels that are closely paired and divergent in parallel at about right angles from the stem. The species also is characterized by it very short calyx to corolla length, relatively short capsules, and large seeds.
