Horsfieldia ardisiifolia is close to species like H. parviflora and H. smithii, both from the Moluccas, all of which have anthers strongly incurved or inflexed into the androecium cup. Horsfieldia ardisiifolia is distinguished by thick winged or ridged twigs, large leaves, coarse hairs on the leaf buds, male buds 4-4.5 mm wide, and a broad androecium with the anthers deeply incurved and clasping each other.
