Combretaceae - Terminalia L.

Description :

  • Trees, usually small in our area but sometimes very tall elsewhere, or rarely shrubs, without scales or microscopic stalked glands
  • Leaves usually alternate, often crowded at ends of branches, sometimes on short shoots, rarely opposite, petiolate or subsessile, usually entire but occasionally subcrenate, often with 2 or more glands at or near base of lamina or on petiole
  • Flowers usually bisexual and male in the same inflorescence (rarely all bisexual), usually in axillary spikes with male flowers towards apex and bisexual ones towards base, rarely in terminal panicles; male flowers stalked, stalks resembling pedicels but corresponding to lower receptacle with abortion of ovary; bisexual flowers sessile
  • Receptacle divided into a lower and an upper part, often scarcely developed, expanding into a shallow cup terminating in sepals (or calyx lobes)
  • Petals 0
  • Stamens usually 10, exserted
  • Disc intrastaminal
  • Style free, not expanded at apex
  • Ovary completely inferior
  • Fruit a pseudocarp, very variable in size and shape but usually 2-winged, usually with an, at least partially, sclerenchymatous endocarp
  • Seeds : cotyledons (where known) spirally convolute
  • x = 12 (7, 13) (high polyploidy, B-chromosomes)
