Flowers 1-few in short clusters or few to many in bracteate racemes, produced on short, axillary branches, greenish to white or yellow, perfect, regular, epigynous. Sepals 5, erect, spreading or reflexed, arising from the summit of a tubular to saucer-shaped hypanthium; petals 5, erect to spreading, shorter than the sepals, inserted at or near the top of the hypanthium; stamens 5, inserted on the hypanthium, alternate with the petals; pistil 2-carpellary, styles 2, separate to below the middle or united nearly to the stigmas, ovary mostly inferior, 1-celled with 2 parietal placentae.
