Melia azedarach, photographed by Forest & Kim Starr.

Belongs within: Sapindales.
Contains: Guareeae.

The Meliaceae are a pantropical family of trees. Some members of the family are significant timber trees, such as species of Cedrela (toon) and Swietenia (mahogany). Molecular data supports division of the Meliaceae into the subfamilies Cedreloideae and Melioideae: the Cedreloideae have the fruit a septifragal capsule, with the seeds usually being winged, while the Melioideae usually have the fruit a loculicidal capsule and the seeds with an aril or sarcotesta (Angiosperm Phylogeny Website).

Characters (from the Angiosperm Phylogeny Website): Trees; bark often rather bitter; secretory cells with resin, etc. present; nodes 5:5; plants often dioecious, but flowers apparently perfect, (3-)5(-8)-merous; calyx often connate, androecium 2x corolla, connate (occasionally 5-30 in a single whorl); gynoecium postgenitally united, opposite corolla, style-head discoid or capitate (occasionally more or less lobed), stigma wet; ovules with outer integument 2-5 cells across, inner integument 2-4 cells across, placental obturator common; archesporium often multicellular; seeds often pachychalazal, coat vascularised, testa undistinguished but thick, endotesta crystalliferous.
