This plant is most nearly allied to A. cyanea, Benth (Warrea cyanea, Lindl.). There is a figure of what seems to be the same species in the drawings made by Schomburgk preserved in the British Museum. It was obtained at Takootoo, and is represented with white flowers, with the base of the lip and the mentum yellow, a few faint purple stains towards the apex of the lip and purple streaks on the face of the column. The fruit deflexed, oblong in shape. It is found also in the region of the Kaieteur Fall.
