Discussion | Plants of Erythranthe exigua are diminutive annuals with few nodes and greatly reduced leaves, corollas, and calyces, wide spreading pedicels, and lavender flowers with small but bilabiate limbs. The species is known only from the San Bernardino Mountains of San Bernardino County and in adjacent Mexico. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
