Description:

  • Lianas climbing by means of the winding ends of young branches, less often shrubs or small trees
  • Leaves alternate, imparipinnate; leaflets entire, persistent or deciduous, petiolate; petiole pulvinate at base; stipules 0
  • Inflorescences axillary or terminal racemes, panicles, or rarely in fascicles
  • Flowers bisexual, or rarely unisexual, regular; androe-cium and gynoecium dimorphic
  • Sepals 5, imbricate or valvate, free or connate at base, caducous or often persistent and sometimes ± accrescent in fruit to strongly so
  • Petals 5, free or sometimes slightly connate at middle, imbricate, rarely valvate
  • Stamens 10, in 2 whorls, free or connate at base, the 5 outer episepalous longer than the 5 inner epipetalous ones, which are often imperfect, hypogynous; filaments free or united basally into a short tube; anthers dorsifixed, 2-thecous, dehiscing lengthwise, introrse
  • Gynoecium superior, of (1-3)-5, free, hirsute, 1-locular carpels; ovules 2, collateral, nearly basal to nearly apical, anatropous to hemitropous
  • Fruit of 1-5 follicles, sometimes connate at base, usually dehiscing by a ventral suture
  • Seed 1(2) per follicle, with or without endosperm, hilum lateral to basal; testa partly to entirely fleshy, sarcotesta (aril) sometimes partly free
