Perianth 8-10 mm long, 5-cleft to far below the middle. Segments with a dorsal, subapical, erect, subulate, obtuse, fleshy, ± 1½ mm long apiculus; the parts exposed in bud fleshy, green outside, overlapped margins membranous pink, inside of perianth pink. Stamens ∞, filaments free, pink or pinkish violet, shorter than the perianth-lobes, anthers darker-coloured. Ovary glabrous, 3-or sometimes 4-celled. Styles as many as cells, white. Capsule included by the perianth, oblong, 9-11 mm long. Seeds long-funicled, shin-ing black.
