Flos in sicco pellucidus. Sepala lateralia late triangulari-falcata, 

 mentum profunde saccatum formaiitia, complicato-mucronata 

 vel caudata. Sepalum dorsale oblongo-lanceolatum, valde con- 

 cavum, acuminatum vel complicato-mucronatum. Petala an- 

 guste lanceolata, ad apicem obtusum vel acutum angustata. 

 Labellum in positu naturali valde decurvum, lateribus inferi- 

 oribus erecto-conduplicatis, marginibus anterioribus valde revo- 

 lutis; lamina expansa lingulata, obtusa. Gynostemium minutum, 

 brachiis binis triangularibus et pede apice unciformi instructum. 

 Plant dwarf. Roots numerous, fibrous, flexuous, puberulent, 

 about .33 mm. thick. Rhizome very slender, about .6 mm. thick, 

 apparently enmeshed in a mass of roots, branched, flexuous, 

 thickly clothed with ovate-oblong thinly scarious imbricating 

 sheaths that become fibrous. Pseudobulbs minute and very in- 

 conspicuous, cylindric, about 2 mm. long, reclining on the rhi- 

 zome, monophyllous. Leaves numerous, 1.2-2.7 cm. long, up to 

 4 mm. broad, linear, acute, gradually narrowed to a very short 

 petiole, rigidly spreading-ascending, in the dried specimen thinly 

 coriaceous, in the living or alcoholic plant very thick, fleshy, sul- 

 cate above and convex beneath. Scapes about 3.6-4 mm. long, 

 one-flowered, articulated near the base, approximate, about six 

 crowded on branches of the rhizome. Pedicellate ovary about 3.7 

 mm. long. Flowers of the Racemosae Section. Perianth pellucid 

 in the dried specimen, segments connivent. Lateral sepals about 

 5.5 mm. long and 4 mm. wide, broadly triangular-falcate and 

 decurved, very oblique, forming a deeply saccate mentum, com- 

 plicate-mucronate or caudate, three-nerved. Dorsal sepal about 

 6.5 mm. long, 1.5 mm. wide below, oblong-lanceolate, acuminate 

 or complicate-mucronate, strongly concave, one-nerved. Petals 

 about 5-6.4 mm. long, 1-1.4 mm. wide below the middle, nar-
