bears a raceme with large, alternate floral bracts which nearly cover the long pedicellate ovaries of the few green-yellow flowers. The sepals are oblong-acute, 5–6 mm long and 2 mm wide; the petals are narrower. The cordate acute lip
is adnate to the column to its apex, has no lateral lobes, and bears a callus consisting of two keel-like ridges near the column apex. The four pollinia are white.
