This differs from V. Griffithii Rchb. f. by the narrow spathulate 



sepals and petals, the small shortly bilobed not flabellate midlobe ofthelip, 



the séries of transverse lamellae beneath the haircushion, the very différent anther. 

 Description from a small herbarium spécimen and an inflorescence 



preserved in alcohol. 



The flowers are described as yellow with a red lip.
