It shares the same type of enlarged fleshy fruit cupule with Cinnamomum crassinervium, but differs in having distinctly stout and quadrangular apical twigs (vs. less angular), 4-locular stamens (vs. 2-locular), cupule perianth lobes not plicate (vs. plicate), and fruit pedicel terete in cross-section (vs. triangular).[1]
