twigs minutely pubescent; leaves spreading, mostly secundate, linear, acute, convex above, sulcate and tomentose beneath, with recurved margins, lower ones glabrous, papillate-punctate, upper ones villous; flowers axillary, solitary, shorter than the foliaceous bracteæ, disposed in a lax or dense, oblong-raceme; calyx campanulate, appressed-pubescent; capsule ovate-globose, at length glabrate; area as large as the capsule. Very near P. axillaris, but the leaves are mostly secundate, very small, and not wider at the base, the upper leaves and the calyx with appressed hairs, the flowers usually smaller. The var. δ. is covered with greyish, appressed hairs, the lower ones glabrous, the flowers larger and more woolly. Leaves about 6 lines long, 1/2 line wide, in var. δ. somewhat longer and wider, in var. β. about 3–4 lines long.
