Flowers: receptacle ± as long as broad, not expanded into ring beneath calyx; petals white, occasionally with obscure yellowish green patch near base, narrowly ovate, nearly equal, 2-6 × 1-2 mm, apex rounded; stamens 6 in 1 series; filaments ± equal, nearly as broad as anthers, tapering from base; anthers linear-oblong, usually at least 1/2 length of filaments. Capsules to 30 × 2.5 mm. 2 n = 16.
