"A little known species which, in the protologue, was compared with V. griffithii Rchb. f., but differs in the narrowly spathulate sepals and petals, the small shortly bilobed but not flabellate midlobe of the lip, the series of transverse lamellae beneath the hair cushion, and the different anther. It has a reddish lip. It is found at higher elevations ie more than 1000 meters, than V. griffithii." Soto Arenas & Cribb 2010
