1 The lower leaf surfaces of Borneo material of H. crassifolia are earlier glabrescent as compared to those in Sumatra and Peninsular Malaysia. 2 Horsfieldia crassifolia may be confused with H. fulva, a species also with more or less coriaceous leaves and a perianth persistent on the fruit, but with a 3-lobed perianth. Sterile specimens of H. crassifolia may be recognized by the coriaceous leaves, which have usually persistent scale-like hairs on the lower surface, and sparse to rather dense irregularly shaped dark dots and dashes. Sinclair (1975: 26) remarked that the species can easily be recognized from a distance by the rusty or cinnamon-brown colour of the lower leaf surface. The species is very constant in habit, characters, and habitat.
