Description:Description - Plant stemless or nearly so, flowering to 8 dm high but often much less. Leaves rather many in a subfasciculate rosette but the outer recurved, 3 dm long, entire; sheaths broadly ovate, 2-3 cm long, the outer ones dark castaneous; blades linear, attenuate, ca 5 mm wide but involute-subulate and appearing narrower. Scape slender, glabrous; scape-bracts narrowly triangular, small, very remote. Inflorescence subpyramidal, very laxly bipinnate or rarely simple, to 3 dm long, few-flowered, glabrous; primary bracts many times shorter than the sterile bases of the branches; branches subspreading. Floral bracts ovate, obtuse, shorter than the pedicels; pedicels slender, 3-4 mm long; flowers spreading. Sepals broadly ovate, obtuse, 4 mm long; petals broadly rounded, 10 mm long, white; stamens included, the anthers elliptic, 1.5 mm long.
