  • Flowers white or pale yellow to pale pink, with or without greenish or brown keels; small; nocturnal; pedicels resembling inflorescence branchlets
  • Tepals fused basally, somewhat spreading, deciduous; cohering above when wilted, circumscissile below, forming a cap on the developing capsule
  • Stamens 6, arising from base of tepals, shorter than tepals; filaments free; anthers oblong, dorsifixed, versatile, introrse
  • Ovary globose to ovoid, with 4-8 ovules in each locule; style terete; stigma apical
