Plants cespitose, forming small colonies of rosettes, acaulescent or caulescent; rosettes usually small, each with ca. 50–85 leaves. Stems erect, to 0.4 m. Leaf blade erect, proximal becoming reflexed, slightly twisted, plano-convex, widest near middle, 50–80 × (1.5–)2–4 cm, rigid, margins entire, filiferous, white, apex acicular. Inflorescences paniculate, racemose distally or entirely, beginning mostly beyond rosettes, ovoid, 50–120 cm, glabrous; proximal branches to 15 cm; bracts erect, distal reduced; peduncle 0.8–1.6 m, less than 2.5 cm diam. Flowers pendent; perianth globose; tepals greenish white, 4–4.5 ´ 1.5–3 cm; filaments 12–15 mm, shorter than pistil; pistil 1.5–3.8 cm; stigmas lobed. Fruits erect, capsular, dehiscent, not conspicuously constricted, dehiscence septicidal.
