Taxonomy
2The species also resembles A. odoratissimus from which it differs in the coriaceous lamina, smooth above and with a repand margin.
3The single collection from Sumatra differs from the (five examined) collections from Sarawak in the absence of long hairs on the leafy twig, petiole, and midrib of the lamina lower surface. The hairs on the stipules are shorter and the dense short brown indumentum of the peduncle is intermixed with longer retrorse uncinate hairs. The apical parts of the peltate interfloral bracts are larger.
1This species shows similarities to A. lanceifolius, particularly the large-leaved specimens from the Malay Peninsula, but differs in the presence of hairs on the lamina below and the ± patent (longer) hairs on the stipules.
