In 1996, Ying Shaoshun considered Phaius calanthoides Ames from Taiwan and Phaius halconensis Ames from the Philippines as the same species and the combination was Cephantheroides halconensis ( Ames ) S. S. Ying in ' Color Map of Orchidaceae from Taiwan '. We did not see the specimen from the Philippines for further study. |
