Umbel persistent, erect, compact, 5–15-flowered, hemispheric, bulbils unknown; spathe bracts persistent, 2, 6–9-veined, ovate, ± equal, apex obtuse or acute. Flowers campanulate, 5–9 mm; tepals erect, white with green or reddish midribs or rarely pink, oblong to lanceolate, ± equal, becoming papery in fruit, margins obscurely to distinctly denticulate-serrulate, apex obtuse to acuminate; stamens included; anthers purple or mottled purple and white; pollen white or gray; ovary crested; processes 3, low, rounded, margins entire; style linear, equaling stamens; stigma capitate, scarcely thickened, unlobed; pedicel 2–5 mm. Seed-coat dull or shining; cells smooth. 2n = 14.
