According to J J Vermuellen - "Bulbophyllum sphaenopus shares the general shape of the lip with B. maxillare (Lindl.) Rchb. f. and B. sannio J. J. Verm., but differs from both in having a sparsely ciliolate dorsal sepal (much less distinctly ciliate than in both other species), and in having acute lateral sepals with straight, only sparsely ciliate lower margins (caudate with thickened tips in B. maxillare, undulating and densely ciliate in B. sannio)."
