Description
|
Epiphytic herbs without pseudobulbs, the plants usually consisting of tufted clusters of several distichous crowns of relatively broad plicate leaves, which are oblong to elliptic-lanceolate, acute, 6-12 cm. long and 1.2-2 cm. wide, the basal portions somewhat contracted into a stout petiole. Inflorescences very short, filiform, more or less arching, or erect scapes about 1.5 cm. long, produced from the lower leaf axils. Flowers small, solitary. Sepals subequal, free, spreading, elliptic-lanceolate, obtuse to subacute, 8-10 mm. long and 3-4 mm. wide. Petals subequal to the sepals, elliptic-lanceolate, acute, 7-9 mm. long and 3-4 mm. wide. Lip undivided, suborbicular, 6-10 mm. long and 6-10 mm. wide when spread out, abruptly contracted at the base into a short claw which is apparently articulated with the base of the column, the apex entire, shallowly emarginate or with an obtuse apicule; disk with a low, fleshy, sessile, bifid callus. Column semi-terete, 5-6 mm. long, the ventral surface below the stigma with a longitudinal keel. Anther and pollinia typical of the genus.

Specimen

CHIRIQUi: without definite locality, Wallis s. n.

|
Note
|
The species was described by Reichenbach from plants presumably collected in Chiriqui Province, the actual locality being unknown. Since there have been several subsequent collections from the Pacific slope in adjacent Costa Rica, there is every reason to believe that this rather obscure record may be good.
