Bulbophyllum mamasaense Wibowo, Juswara & J. Champ., sp. nov.
Diagnosis: Bulbophyllum mamasaense is morphologically similar to B. pubiflorum Schltr. in its habit, and B. kiamfeeanum J.J.Verm. & P.O’Byrne in its ovate lip. However, B. mamasaense has distinct 3-angled pseudobulbs, oblong and larger leaves, flat lateral sepals compared to B. pubiflorum, and is different from B. kiamfeeanum by its lip forming a canal at the base and presenting a verrucose surface, while B. kiamfeeanum has a rounded callus and a glabrous surface (Table 1).
Distribution: Mesawa District, Mamasa Regency, West Sulawesi, Indonesia.
Etymology: The specific epithet “mamasaense” was named after the location [Mamasa Regency] where this species was first discovered.
