Description Stout epiphytic herbs with ovoid or subcylindric, often laterally compressed or furrowed pseudobulbs, the apex with 1-4 broadly plicate leaves, the plants considerably resembling a robust Stanhopea. Inflorescences elongate, pendulous or erect racemes from the base of the pseudobulbs. Flowers usually many, fleshy, relatively large and conspicuous. Sepals subequal, broadly concave, the dorsal sepal free, the laterals usually connate at the base. Petals subequal to the sepals but usually smaller. Lip 3-lobed, fleshy, concave, with a concave or subsaccate, basal claw or hypochile, lateral lobes large, erect, triangular or subreniform, the apical lobe carinate, concave or spreading; disk fleshy, with variously shaped appendages. Column erect, usually pubescent, somewhat arcuate, subclavate or narrowly winged, without a foot. Anther terminal, operculate, incumbent, 1- celled or imperfectly 2-celled; pollinia 2, waxy.
Note A genus of robust American epiphytic orchids ranging from southern Mexico to Venezuela and Ecuador. Vegetatively they often considerably resemble a stout Stanhopea, but are most closely allied to Peristeria, although the complex structure of the lip in some species more nearly approaches that found in the former genus. Schlechter in his monograph distinguishes 13 species, the major separations in his key being based on color. No attempt has been made to evaluate these specific concepts, except that Acineta chrysantha and A. sellk-turcica seem to be one entity on the basis of the evidence now available. Of the two valid species that have been listed for Panama, only one, A. chrysantha, has been found in recent years. How- ever, the wide distribution of A. superba in adjacent Colombia would increase the possibility that it has been, or will be found in Panama.
Key a. Lip in profile with a broadly emarginate indentation or constriction below the lateral lobes, separating the hypochile from the epichile, the basal claw or hypochile subsaccate; apical lobe of the lip about 1 cm. long ..................................................................................... 1. A. CHRYSANTHA aa. Lip in profile deeply gibbous and continuous, without an emarginate indentation below the lateral lobes; basal claw or hypochile rectangular- concave, not subsaccate; apical lobe of the lip about 2 cm. long .......... 2.
