Inflorescence: cyme, ± umbel-like, open, 1–several-flowered; pedicels recurved in fruit, bractlets 0. Flower: hypanthium shallow, bractlets 5, narrower than sepals; sepals, petals ± obovate, generally white; stamens 20–35, filaments ± flat, pollen sac 1, horseshoe-shaped; pistils many, ovaries superior, jointed to stout style on side.

Unabridged note: Characters include calyx orientation, fruit size used to define subspecies despite evident lack of taxonomic value.
