Discussion

R. K. Vickery (1992) noted that yellow-flowered morphs of Erythranthe verbenacea occur in a population at Vasey’s Paradise in the Grand Canyon (Coconino County), 32 miles downstream from Lees Ferry.

Populations of Erythranthe verbenacea in the Oak Creek Canyon area in southern Coconino County, Arizona, have leaves with a narrow, lateral, undulating, purple stripe across the mid lamina. The coloration is retained even in dried specimens.

In Utah, Erythranthe verbenacea is known only from the Zion Canyon area.

Molecular (P. M. Beardsley et al. 2003) and morphological (G. L. Nesom 2014b) data indicate that Erythranthe verbenacea is sister to E. eastwoodiae.

Erythranthe gemmipara is known only from Grand, Jefferson, Larimer, and Park counties in north-central Colorado. Flowers in this species are uncommon, and seed set has not been observed in natural populations; reproduction in nature appears to be solely asexual via overwintering propagules (bulbils) formed in leaf axils. Two meristems are initiated in each axil. The proximal meristem produces a pair of starch-thickened storage leaves, a rudimentary axis, and a distal pair of preformed leaf primordia that enclose the shoot apical meristem. Root primordia are present within the first node of the bulbil. The petiole of the subtending leaf expands laterally and folds adaxially to enclose the developing bulbil, and entangled trichomes along the petiole margins secure it following leaf abscission and dispersal. The leaf blades commonly are deciduous, leaving the bulbil still attached (M. R. Beardsley 1997).
