subdensum dispositi. Sepala lateralia late ovata, acuta, cari- 

 nata. Sepalum dorsale ovato-lanceolatum. Petala ovato-oblonga, 

 membranacea. Labellum saccatum, ecarinatum, in laminam ob- 

 longam productum. Gynostemium ad apicem tridentatum. Ro- 

 stellum bifidum. 



Rhizome stout. Pseudobulbs semi-fusiform, 4-6 cm. high, 

 ±1 cm. in diameter at about the middle, monophyllous. Leaf 

 ±3 dm. long, ±4 cm. wide, oblong-lanceolate, petiolate, atten- 

 uated at both ends, longer than the flower shoot, rather rigid 

 when dry, conspicuously seven-nerved. Petiole about 1 dm. long. 

 Flower shoot from the new growth, synanthous, up to 2 dm. 

 long including the raceme, concealed by five or more large, 

 imbricating, acute, nervose sheaths which rise from the base 

 of a mature pseudobulb. Raceme about 8 cm. long, sub-densely 

 flowered, erect, rigid ; bracts deciduous leaving an annulate scar. 

 Pedicel and ovary about 1 cm. long, glandular pubescent. 

 Flowers white, yellow when dry, somewhat globose. Lateral 

 sepals 8 mm. long, about 5 mm. wide, broadly ovate, acute, car- 

 inate, at base forming a rounded mentum. Dorsal sepal about 

 8 mm. long, ovate-lanceolate, acute. Petals about 8 mm. long, 

 4 mm. wide, ovate-oblong, acuminate, acute, membranaceous. 

 Labellum 8 mm. long, deeply saccate at base, prolonged in front 

 into an oblong round-tipped plate 6.5 mm. long, 3 mm. wide, 

 abruptly reflexed in front of the rounded scrotiform sac. The 

 sulcate disc and sac ecallose, but on each side in front of the 

 sac the lip is conspicuously longitudinally thickened. Gynoste- 

 mium with two rounded appendages at base; terminal wing 

 three-toothed, the central one obtuse, semi-orbicular, the lateral 

 ones divergent and much smaller, ovate, subobtuse. Rostellum
