Type specimen: "N. Granat"
The lithograph illustrated at left was published in 1880 in Les Orchidees (Pl. 40, pg. 38), by Paul Emile de Puydt.
Bright rose-lavender flowers borne on a terminal raceme; the rachis is strong and a dark maroon-purple color. The lip bears a white and yellow callus, and there is a longitudinal central white line on the dorsal sepal and petals. Column, anther, and twisted pollinia are white. Lip approx. 10cm-long; column approx. 3cm-long; sepals and petals 6-8cm-long. It is found growing very close to the Colombian border.
"In Venezuela this species has been found growing as a very robust terrestrial at about 2000m. altitude in the Sierra de Perija in the state of Zulia. This species is notable not only for the beauty of its flowers but also for their long-lasting character, and for the fact that up to six flowers can be borne on a single raceme-- a pleasant contrast with most Sobralia flowers which are developed singly and seldom last more than a day." (Dunsterville 1987)
