Featured in Wildflowers of North America – Sept 30, 2011
LEWIS’ MONKEY-FLOWER Mimulus lewisii Lewis’ monkey-flower is a showy, herbaceous perennial with erect stems ascending from rhizomes. The leaves are glabrous to slightly hairy, lance-shaped, and unevenly toothed. The pink-purple, irregular corollas are two-lipped with two lobes above and three lobes below, while the throat has two bright yellow patches.
HABITAT/RANGE: Thiscommonmoun-tain wildflower grows in dense clumps along moist, wet streams, ravines and seepage areas. Ranges from Alaska south to Utah and California. Blooms late June through August.
FACTS/USES: Both the common and specific names pay tribute to Captain Meriwether Lewis, the explorer who first described this plant. The bright rose-pink flowers are attrac-tants for pollination by insects and hummingbirds. As nectary guides entice them into the funnel-shaped throat, anthers, projecting from the roof, dust their backs with pollen.
