 Petala ovato-lanceolata, valde acuminata, quam sepala multo

 longum, scabridum, lingulatum. Gynostemium circiter 5 mm.

By far the largest species of the genus in the Philippines and 



one of the largest heretofore discovered. In the dried specimens 



from which the description was prepared the pseudobulbs are 



notably elongated, and as thick at the summit as at the base. The 



lateral sepals are rough on the outer surface, and conspicuously 



keeled. The petiole of the leaf together with the pseudobulb 



exceeds the erect inflorescence.
