This is much like the last, and is often very handsome. In the crevices of the sea-cliffs at La Jolla it makes tangled thickets of woody stems and dark green foliage, ornamented with many scarlet or rich deep-red flowers, with a velvety surface like that of a pansy and with orange ribs in the throat. This is common throughout California.
There are many kinds of Mimulus, or Monkey-flower, usually growing in moist places, with erect or slanting, juicy stems; leaves opposite, usually toothed; flowers generally handsome, on flower-stalks from the axils of the leaves; calyx covering the tube of the corolla, bell-shaped, five-angled and five-toothed, upper tooth usually larger; corolla two-lipped, the upper lip with two lobes, erect or turned back, the lower with three, rounded, spreading lobes, the tube not swollen at base and with a pair cf ridges within on the lower side; stamens four, in pairs, not inclosed in the upper lip, their two anther-cells spreading apart, no rudiment of a fifth stamen; style threadlike, stigma with two, flat, spreading tips. When an insect alights it touches the stigma, which immediately folds its tips together, thus exposing the anthers, so that the insect becomes dusted with pollen. This can be observed by touching the stigma with a pencil. The odd little grinning face of these flowers suggested both the common name and the Greek, derived from "ape."
