sterile bract at the upper part than the middle, about 3-3J decim, includ- 

 ing the raceme. Kaceme laxly flowered, 9-13 cm. long ; rachis slender, 

 pubescent ; bracts erect-patent, shorter than . or equal to the pedicel in 

 length, 6-14 mm. long, ovate-lanceolate, acuminate, entire, nearly glabrous. 

 Flowers 5-7 in number, cernuous, of middle size. Perianth half patent, 

 glabrous, yellow-green ; outer 3 equal in length, narrowly oblong in the 

 superior (truly inferior) one, oblong-lanceolate and a little falcate in the 

 lateral ones, attenuated below, longer and more narrowly attenuated above 

 with an obtuse tip, entire but very slighty crispate, 5 -nerved, 16-1 6 J mm. 

 long, 4-4J- mm. broad ; inner 2 much narrower and somowhat shorter than 

 the outer ones, linear, acute, entire, slightly crispate, 3-nerved, about 15 

 mm. long, If mm. broad. Labelluni calcarate, shorter than the perianth, 

 the basal portion adnate to the gynostemium throughout the length where 

 it forms a hollow, passing to the calcar behind, provided with dense hairs 

 turned inwards ; limb yellow, about 9 mm. long, 8-8 J- mm. broad, thin, 3- 

 fid with obtuse sinuses between them, 3-carinate on the lower half, the 

 outer carina about 1J mm. wide, cristate, connected at its basal end to 

 the basal obtuse projectures, the middle carina much narrower than the 

 lateral ones ; midlobe oblong-ovate, with a minute sharp point 1 mm. in 

 length at the apex, crispate on the margin, with several veins towards the 

 centre ; lateral lobes spreading, shorter than the midlobe, but nearly equal 

 to it in width, shortly oblique-ovate, rounded-obtuse at the apex, irregular- 

 ly subcrenate towards the apex, with several veins ; calcar short, about 5 

 mm. long, cylindrical with an acutish-obtuse tip, curved downwards, nearly 

 glabrous externally but very slightly pubescent within. Gynostemium oblong- 

 cylindrical, 5 mm. loug, 2 mm. across ; clinandrium turned upwards, deeply 

 concave, with entire margin ; rostellum distinctly produced, 2— fid into acute- 

 falcate beaks. Anther opercular, ovate, narrowed towards the front end, 

 convex, thicker crispate and angular on the back near the base, with 2 

 deep anther-cells ; pollinia 8, the fours larger than the rest, narrowly ob- 

 ovate, compressed, yellow, waxy; caudicle short and narrow: retinaculum 

 minute, ligulate. Ovary cylindrical, gradually narrowed below, arcuate, 

 pubescent, grooved, 1J-2 cm. long including the pedicel ; pedicel stout-fili- 

 form, subequal to the ovary in length, thinly pubescent. Immature cap- 

 sule obovate-cylindrical.
