Calanthe cootesii M.A. Naive from Mt. Maagnaw, Kitanglad Mountain Range, Bukidnon, is described and illustrated. Morphological diagnostic characters of related species of the genus are discussed. Though similar to C. brassii Ormerod, the new species is clearly distinguished by having a marked difference in the shape of the lip and the reflexed and recurved floral segments. It is also allied to C. davaensis Ames, but the new species is clearly distinguished by having smaller and greenish flowers with an indistinct spur.
