Rhizomes horizontal, branching, thin. Scapes 1–2, round in cross section, 0.7–2 dm, slender, becoming taller and more robust after flowering, glabrous. Bracts very short-petiolate, subsessile or sessile; blade dark green with maroon undertones when young, not mottled, 3–5 major veins from base, oblong to lanceolate-obtuse, 2.5–8+ × 1–3 cm, not glossy, apex obtuse. Flower above bracts, erect, odorless to faintly sweet, pedicellate or sessile; sepals conspicuous, spreading to same plane as petals, dark green with maroon undertones when young, oblong-lanceolate, 15–30 × 5–10 mm, margins entire, apex obtuse to strongly rounded; petals of short duration, spreading-ascending, exposing stamens and ovary, weakly recurved in distal 1/2, white, aging to deep rosy pink abaxially, veins not engraved but major petal veins clearly visible, oblong to narrowly lanceolate, 1.5–3 × 0.5–1.5 cm, thin-textured, widest above base, margins strongly undulate, quite variable in petal width and degree of undulation between individuals and populations, apex obtuse to weakly acute; stamens erect-spreading, 8–10 mm; filaments pinkish purple to white, ± equaling or slightly shorter than anthers, slender; anthers ± straight, pale lavender or yellow, 3–8(–10) mm, thicker than filaments, dehiscence introrse; connectives not extended beyond anther sacs; ovary conspicuous, white, ovoid, obscurely 6-angled, 2.5–8 mm, attachment narrower than ovary; stigmas confluent with style, greenish white to white, distally 3-lobed, lobes linear (threadlike), long-spreading, 3–12 mm, uniformly thin and threadlike; pedicel stiffly erect to leaning, 0.5–2 cm, or absent to much reduced. Fruits white or pale greenish, ovate, 1–1.5 cm, pulpy, moist but not juicy. 2n = 10.
