Taxonomy

The leaves of Aglaia crassinervia resemble A. rufinervis, but there are fewer leaflets and the indumentum is of peltate scales with a fimbriate margin rather than stellate hairs or scales. The length of the fimbriate margin on the peltate scales varies. When the scales have a long fimbriate margin, it is sometimes difficult to distinguish A. crassinervia from A. sexipetala. That species has numerous stellate scales on the lower leaflet surface and some compact stellate hairs interspersed; the latter are absent in A. crassinervia.
