Taxonomy

Aglaia cumingiana resembles A. lawii and A. oligophylia in its foliage, but it is distinguished by the indumentum, inflorescence and fruit. In some respects, especially flower structure, A. cumingiana is like A. parviflora, but the latter is more robust, with larger leaves and twigs; the reticulation on the leaflets is not prominent; peltate scales with a fimbriate margin are numerous on the midrib be- low, while stellate scales are more abundant on the inflorescence; the fruits have dense scales on the outside.
