subcoriaceum. Scapus brevis, uniflorus. Flos mediocris, in sicco 

 pellucidus. Sepala lateralia late ovata, obliqua, apice acuta et 

 dorso carinata. Sepalum dorsale oblongum, valdissime concavuin, 

 acutum. Petala oblonga, obliqua, leviter falcata, acuta. Labellum 

 anguste triangulari-cordatum, valde decurvum, carnosissimum,

 binis spathulatis decurvis et pede apice unciformi praeditum. 



Plant rather slender. Roots few, stout, rigid, apparently un- 

 branched, longitudinally sulcate, ±1 mm. thick, produced near 

 the pseudobulbs. Rhizome about 2.5 mm. thick, creeping, woody, 

 striate-sulcate in the dried specimen, provided with close but not 

 imbricating sheaths. Sheaths tubular, loose, scarious, up to 9 mm. 

 long. Pseudobulbs about 3.5 cm. distant, about 2.2 cm. high, 

 cylindric or very narrowly pyriform-cylindric, monophyllous, 

 closely rugose in the dried specimen, enveloped by a loose sca- 

 rious sheath that surpasses the summit of the pseudobulb and 

 becomes fibrous in development. Leaf about 13.5-14.2 cm. long, 

 1.65-1.95 cm. broad, linear-oblong, somewhat falcate, apex ap- 

 parently acute but really obtuse and complicate, below cuneate- 

 narrowed to a sulcate petiole 1-2 cm. long, subcoriaceous, many- 

 nerved with the mid-nerve slightly sulcate above and sharply 

 carinate beneath. Scape inclusive of the scarcely perceptible 

 ovary about 5.3 cm. long, one-flow^ered, provided with two 

 sheaths, the lower infundibuliform and about 1.5 cm. long, the 

 upper loose suborbicular acute, dorsally carinate at the apex and 

 about 7 mm. long. Flower glabrous, pellucid in the dried speci- 

 men. I^ateral sepals about 1.5 cm. long, 6 mm. wide at the base 

 and 1 cm. wide in the middle, broadly ovate, oblique, acute and 

 dorsally carinate at the apex, with about nine nerves. Dorsal 

 sepal about 1.7 cm. long, 6.1 mm. wide, oblong, very strongly 

 concave or cucuUate, acute and dorsally carinate at the apex.
