Stems (rootstocks) buried, creeping and horizontal, several inches long, sending up simple branches, 3 to 9 inches high, each of which bears a whorl of five to ten leaves at the summit, and a few scale like leaves on the lower part of the stem. Leaves thin, lanceolate or oblong-lanceolate, sharp pointed at both ends, sessile or nearly so, 11/2 to 5 inches long, one-third to 11/4 inches wide, the margins minutely crenulate. Flowers one-third to one-half of an inch broad, white, one to three or four, on very slender peduncles at the summit of the leaf-bearing stems; sepals very narrow and spreading, usually seven in number; corolla with five to nine (usually seven) oblong or somewhat obovate, pointed segments. Fruit a small, globular capsule shorter than the sepals.
