Flower Size

Found in Sumatra and Sabah Borneo in montane forests at elevations of 400 to 1100 meters as a large sized, hot to cool growing, viney terrestrial with a long and climbing stem carrying ovate-oblong, acuminate, channeled into the petiolate base leaves that blooms on almost sessile, not branched, thick, strongly angled, 1.48 to 2.4" [3.7 to 6 cm] long, densely many flowered inflorescence with spreading, broadly triangular, obtuse floral bracts.

"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
