Bulb globose, 2–3 cm in diameter, outer tunics blackish, disintegrating, inner tunics white. Scape 20–50 cm long above ground, slightly flexuous, cylindrical, 2–3 mm in diameter, basal part green or flushed carmine. Leaves 3–5, linearlanceolate, 2–5 cm wide and 7–25 cm long, green, with narrow white margin, smooth. Spathe most often completely split in 2–3 triangular parts, initially adpressed to the pedicels and later deflexed, faintly purplish with somewhat darker veins. Inflorescence semispherical at flowering time, subspherical in fruit, dense, 4–8.5 cm in diameter. Pedicels cylindrical, up to 2 cm long, almost equal, greenish or slightly carmine-flushed. Perigone nearly campanulate. Tepals obovate-orbiculate, obtuse at apex, often undulate, 3.5–6 mm wide and 6–7 mm long, white with green midvein. Filaments 4/5 as long as tepals, fleshy, basally united, triangular, white. Anthers yellow. Ovary depressed-globose with three furrows, dark purplish-black. Style cylindrical. Capsule globose, with three longitudinal furrows, 5–6 mm wide. Seeds ovate to broadly ovate, rugose, blackish, 3–4.2 mm long. The seed testa cells angularly round, convex, with many prominent verrucae and omega-like undulations with moderate wavelength. Flowering in May–June, fruiting in June–August. 2n = 16.
