than the laterals, similar to the 1-nerved, somewhat falcate, linear-

 long, about 2 mm. wide ; lateral lobes broadly ovate-falcate, obtuse, 

 with a thickened, partly free callus at the base of each; middle 

 lobe deeply emarginate, mucronate ; sac or depression oblong,

A compact epiphyte about 6 cm. high, with a dense distichous 

 inflorescence of white fragrant flowers. Pseudobulbs fusiform, 

 1-1.5 cm. long, rugose when dry, monophyllous. Leaves linear- 

 oblong, shortly petioled, coriaceous, acute, 2.5-4 cm. long, 3-5 

 mm. wide, prominently 3-nerved, the outer nerves marginal, giv- 

 ing the leaves a marginate aspect (at least when dry). Petiole 

 about 3 mm. longf. Peduncle below inflorescence shorter than or 

 equalling the leaf, rather strict, filiform. Inflorescence 1.5-2 cm. 

 long, 4—5 mm. through, densely flowered. Bracts broadly ovate, 

 obtuse, erose, dentate on the margin, 2.5 mm. long, exceeding the 

 ovary and clasping the base of the perianth. Lateral sepals lance- 

 olate, acute, 1-nerved, 3 mm. long, less than 1.5 mm. wide. Upper 

 sepal similar to, but narrower than, the laterals. Petals linear- 

 lanceolate, acute, 1-nerved, 3 mm. long, slightly less than .75 mm. 

 wide. Labellum 3-lobed, with large falcate, obtuse, diaphanous 

 lateral lobes, 1 mm. long, and with a minute trilobed middle lobe 

 which is fleshy and passes into fleshy calli, situated one on each 

 lateral lobe, on the inner margin near the base ; on the median line 

 a minute papilla. Column with a rostellar process protuberant 

 from the front. Anther very large in proportion to the size of the 

 minute column.
