A delicate little plant, from three inches to a foot high, rather hairy and sticky, with very slender branching stems, yellowish-green, toothless leaves, and bright flowers, about three-quarters of an inch long, with almost no flower-stalks; the corolla-lobes pink, veined with purple, the tube crimson, with two yellow ridges in the throat. A patch of these little flowers scattered over a sandy slope in Yosemite, sometimes growing with a tiny blue and white Lupine that likes the same sort of place, is an exceedingly pretty sight. It grows in the mountains, preferring moderate altitudes, becoming lower and deeper in color in higher places.
