SITF confirms this plant as Bulbophyllum odoratum var. obtusisepalum (Jan 2026). Bulbophyllum odoratum var. obtusisepalum, which Kew POWO considers synonymous with Bulbophyllum odoratum, was validly published in Blumea 5: 748 in 1945 and therefore can be used in the identification. The difference between the variety and the type is in its short, stubby (obtuse) sepals. The type has elongated, narrowly pointed sepals, creating a distinctly different image. Vermuellen's 2011 "Orchids of Sulawesi" show photos of B. odoratum as well as on the IOSPE, OW and Orchidroots. This species should not be confused with Bulbophyllum odoratissimum (Sm.) Lindl. ex Wall, which has an umbellate inflorescence.
