Habit	Tufted, perennial herbs, the stems simple, glabrous, 1.7-2.8 mm. wide and up to 3.2 dm. tall.
Leaves	Leaves mostly basal, glabrous, narrowly linear, up to 2 dm. long.
Flowers	Inflorescence borne singly, subtended by a pair of green, glabrous bracts, the outer 27-48 mm. long, 14-17 mm. longer than the inner, united at the base, the inner with the keel evenly curved, the tips obtuse to acute; tepals 6, pale blue, the bases yellow, 10-14 mm. long, oblong, rounded, with a short bristle; stamens 3, the filaments fused to near the tip; ovary inferior.
Fruits	Capsule 3-celled, tan to medium brown, globose, 4-5 mm. long.
