Umbel persistent, erect, compact, 8–20 (–30) -flowered, globose to conic, bulbils unknown; spathe bracts persistent, 3, 9–13-veined, broadly ovate, ± equal, apex abruptly acuminate. Flowers conical to campanulate, 7–10 mm; tepals strictly erect, dull purplish with darker midveins, ovate, ± equal, becoming membranous, withering in fruit, margins entire, apex obtuse; stamens equaling tepals or ± exserted; filaments smooth proximally; anthers purple; pollen yellow or gray; ovary crestless or crested; processes 6, central, rounded, minute, margins entire; style linear, slightly longer than stamens; stigma capitate, scarcely thickened, unlobed; pedicel 6–10 mm.
