This member of the Orchidaceae family was given this name by Robert Allen Rolfe in 1890. It is found in the cloud forests of northern Bolivia and Peru, growing in the trees with quite some water and some sun. The pseudobulbs will grow to four centimetres in diameter, the plant up to 30 centimetres in height, 45 with the bright red flowers. Its name is derived from the Greek word ὀγκος, (onkos), meaning 'swelling'. This refers to the callus at the lower lip. The species name after Noël Pierre Joseph León Bernard, 1874 - 1911, a French botanist, famous for the discovery of the symbiotic germination of orchid seeds.
