Very beautiful, from two to three feet high; with purplish stems, smooth leaves, and flowers an inch long, with a bright scarlet, funnel-shaped corolla, not much two-lipped, the stamens not protruding. These graceful wands of vivid color are conspicuous in the Grand Canyon. P. centranthijblius, common in California, is similar, the corolla less two-lipped, and has very smooth, thickish leaves. P. Bridgesii, found in Yosemite, is similar, but the corolla is decidedly two-lipped.
