Vine, glabrous. Pseudostipules and leaves similar to A. hians. Flowers axillary, solitary; pedicel twining, 7-8 cm long; ovary 3-4 mm long, perpendicular to the pedicel; hypanthium present; perianth: utricle 5-6 x 2-3 cm, tube cylindric, up to 1.5 cm, superior lobe paddle-shaped, up to 12 cm long, 4 cm wide in the distal part, inferior lobe not seen in the Guianan material.

Notes

Two old specimens of this species are preserved at P. One, in Herb. Richard, might have been collected in French Guiana by Leprieur, the other from Herb. Mocquin-Tandon seems to be of horticultural origin. The presence of this species, originating from southern Brazil (2 specimens studied), in the wild in the Guianas is very doubtful.
