Though the species is as yet only known in fruit, it stands out by the glabrous, subcoriaceous leaves with obtuse to sometimes slightly concave base and clearly trabeculate venation with close reticulations.
It may be related to A. foveolata and A. papillifolia, but differs by these leaf characters.
