A perennial Orchid, about 3-10 cm. high, glabrous. Rhizome hypo- 

 greous, often curved, somewhat thicker above, pale, flaccid, covered with 

 root-hairs, provided with a few (about 2) minute colourless scales above, 

 at each axil of scales with a short pale and slightly fleshy branch ; the 

 tuber small, simple, globose to ellipsoid, attaining about 3 mm. across. Stem 

 slender, angulate, pale green, furnished with the single leaf above the middle 

 and a minute scale at the base. Leaves small, semi-amplexicaul, ovate, 

 acuminate, entire and more or less crispate on margin, green, the midrib 

 inconspicuous, the lateral vein 1 on each side and arcuate ; those of sterile 

 stem few, petiolate, vaginate at the base, orbicular, acute. Raceme short, 

 terminal, loosely flowered ; rachis fiexuous, angulate ; bracts patent, sessile 

 and semi-amplexicaul, similar to leaves in form but slightly smaller. Flower 

 large in proportion. Perianth subequal, linear, acuminate, entire, mem- 

 branaceous, 1-nerved, somewhat incurved. Sepals bearded with long and 

 few hairs on both basal margins, more or less narrowly inflexed on margin, 

 light green, but the superior one also shaded with purple in the lower half ; 

 the superior one 4 mm. long ; lateral ones shorter and 2^ mm. long, hidden 

 under the label lum when flower expanded. Petals not bearded on the 

 basal margins, light green and shaded with purple below, 3| mm. long. 

 Labellum ample, patent, orbiculate, scarcely short-attenuated below, entire 

 but minutely crenulated on the front margin, 4 mm. across, very light purple, 

 but deep purple vertically in centre ; appendage directed to the front, much 

 shorter than the labellum and li mm. in length, cut down to the midway 

 into two lobes of the upper and lower, purple ; lobes shortly bifid at the 

 apex, the upper one a little shorter. Column light green, 3J mm. long ; 

 appendage minute and emarginate; clinandrium with an obtuse short 

 rostellum in the front sinus ; anther-valves minutely tuberculate on the
