Similar to B Osyricera sharing the short, denticulate petals, the operculum with a papillate extension, but the flower dimensions and the shape of the labellum separate them. Also B erosipetalum has a sinilar habit but the inflorescence is shorter, the lip and petals siffer and the stelida is trident-like.
