is found only in the southern half of the Sierra Nevada, California, where it is easily recognized on account of its small, bicolored flowers; the upper lip, shallowly divided into two notched lobes, is deep purple, white the lower lip, more deeply divided into three notched lobes, is yellow, flecked with purple (and hairy) towards the base. Sometimes both lips are yellow, however. Beneath the lobes, the narrow, cylindrical corolla tube is around 0.4 inches long, while the calyx is much shorter, divided into five equal lobes, lacking marginal hairs. Flowers are attached by stalks of up to one inch.
Plants have a sparse covering of short, glandular hairs. Leaves are short and linear, with tapered bases and blunt-pointed tips, and are flat, lacking rolled-under margins. Flowers are produced in open clusters, at the tip of the stems and from the upper leaf nodes.
