Calanthe devogelii differs from the related widespread C. triplicata (Willem.) Ames in being a much smaller plant with much smaller flowers, the sepals, petals and lip scarcely 0.7 cm long at the most and the spur only 0.5 cm long. The sepals and petals are ventrally sparsely pubescent. (after Cribb, Ormerod & Dudley 2011)
