Whole plant 11-22 cm. high. Rhizome short, ascending or erect ; 

 roots filiform, with root-hairs. Stem erect, slender, glabrous below the 

 leaves but above them pubescent with patent glandular hairs including the 

 rachis of the raceme, provided with short, adpressed, membranaceous and 

 remotely placed two sheaths at the base. Leaves 2, oppositely approximate, 

 situated in the middle of the whole plant, patent, sessile, ovato-semiorbicu- 

 late, or subreniform-semiorbieulate, abruptly cuspidate at the apex, broadly 

 truncate or truncato-subcordate and in centre very slightly produced at the 

 base, minutely crispulate on the entire margin, glabrous, membranaceous, 

 13-25 mm. long, 10-31 mm. wide; main nerves 3, with a vein between 

 main nerves and in their outsides ; veinlets loosely anastomosing ; reduced 

 leaves none or only one, squamiforrn, ova to-subulate, membranaceous, 1- 

 nerved. Raceme erect, loosely 3-9-flowered, 3-5^ cm. long ; rachis gracile, 

 often subflexuous; bracts {Fig. IV. 1.) 

 small, patulous or erect-patent, distinctly 

 shorter than pedicels, ovato- subulate, 

 membranaceous, glabrous, 1-nerved, 

 1^-5 ram. long. Flowers small, oliva- 

 ceo-purpurascent ? ; pedicels gracile, 

 erect-patent, glabrous or subpuberulent, 

 3-8 mm. long. Perianth equal in 



length, obtuse, membranaceous, 1-nerv- 

 ed, 3-4 mm. long. Sepals reflexed ; 

 the superior one {Fig. IV. 2.) oblong- 

 lanceolate ; lateral ones {Fig. IV. 3.) 

 similar, but hardly oblique in form. 

 Petals {Fig. IV. 4.) slightly broader 

 than sepals, oblong. Labellum {Fig. 

 IV. 5.) twice as long as the perianth, 

 flabellato-obcordate with ovato-oval or 

 oval-elliptical rounded- obtuse often subcreuulate divergent lobes, with a 

 minute depressed-deltoid point in the bottom of open sinus, broadly cuneate 

 below and shortly attenuated at the base, on each side near its base fur- 

 nished with a small (lJ-limm. long.) obovato-elliptical or subspathulato- 

 oblong obtuse tooth (turned upwards and parallel to the column), 5-6-| mm. 

 long, 4|-6mm. broad, flabellately veined, the median nerve thicker. 

 Column 2-2|nm. long, straight; clinandrium deeply concave, the dorsal 

 edge thin and pauci-crenulate ; anther lato ovate, obtuse ; rostellum broad ; 

 Ovary obovoid or obovoid-oblong, glabrous, 2-3 mm. long.
