Description
Trees or pachycaul treelets with cicatrose twigs.
Leaves imparipinnate, leaflets opposite.
Inflorescences axillary to supra-axillary, male flowers in panicles, female and hermaphrodite in long spikes or racemes, rarely panicles.
Petals 3, imbricate, united with staminal tube basally.
Staminal tube globose to deeply cyathiform; anthers 3–8, glabrous, inserted within tube.
Ovary 3- (or 4-)locular, each locule with (1)2 collateral to superposed ovules; style stout; stylehead conical to truncate, 3-angled or with impressions of anthers.
Fruit a 2- or 3- (4-)valved, loculicidal capsule, locules 1- or 2-seeded.
Seeds arillate, cotyledons plano-convex, collateral (?) united; radicle small, superior, included.
Distribution

Taxonomy
All three species were originally referred to Andersonia Roxb. (or Amoora), i.e. Aglaia Lour., to which Aphanamixis is very closely related. Except for the apparent unity of the cotyledons (a feature not investigated in all Aglaia spp. so far), there is no other macroscopic character which separates them absolutely. At the microscopic level, only one Aglaia species has the 4-colporate pollen grains found in Aphanamixis and the wood of the latter differs from that of the Aglaia species formerly included in Amoora in having confluent and banded paratracheal parenchyma (T.D. Pennington, l.c.).
