Leaves: Leaves simple. Tufted near the tips of the stems. Blades narrowly oblong–lanceolate to narrowly elliptic or sometimes elliptic, 10–30 cm long, 1.5–5 cm wide, blades undifferentiated from petioles. Apex acute to acuminate. Base slightly narrowed at base and sessile, or gradually attenuate to a winged petiole. Surfaces glabrous or lower surfaces sometimes appressed pilose, thick, coriaceous. Margins minutely and remotely denticulate or entire. (3–)5–9-veined, the veins more or less converging toward base. Petioles up to 5 cm long, winged. Stipules absent.

Flowers: Flowers in scapes usually several, 10–50 cm long, spikes (7–)11–28 cm long, glabrous to sparsely pilose, flowers densely crowded, sometimes spike somewhat interrupted, each flower spreading at nearly 90° angle to the axis. bracts lanceolate,1.2–3 mm long, glabrous but sometimes woolly at base, bracteoles absent. Flowers bisexual (perfect). Calyx of 4 sepals, subequal, distinct, elliptic to elliptic–ovate, 1.8–3.2 mm long, scarious except on midrib, glabrous or ciliate, apex sometimes minutely erose. Corolla salverform, 4-lobed, scarious, persistent in fruit, the tube covering the upper part of the capsule, lobes spreading, 1.5–2 mm long.
