The species is recognized by the tall plants, to 60" [1.5 meters], the leaves ovate-elliptic, somewhat arched of the main stem, 1.4 to 2.4" x .08 to .96" [3.5 to 6 x 2 to 2.4 cm]; flowers green, dotted purple, the sepals dorsally verrucose, .36" [9 mm] long, the lip with the disc fleshy, midlobe trapezoid.
