 the stems very short and slender: leaves rather narrowly elliptical, 

 3-toothed at the apex, attenuate to the slender more or less elongated 

 petiole, bright green, faintly margined and faintly few-nerved, the 

 blade about an inch long : peduncle very short and slender from be- 

 low the base of the leaf, the 3-6-flowered raceme about equalling the 

 petiole ; bracts ovate, acute, sheathing ; pedicels a line long: perianth 

 pale yellow, spreading; sepals lanceolate, § line long, the lower united 

 to below the middle, subfalcate, acuminate, nerveless, the upper acute, 

 faintly 1 -nerved ; petals lineax'-lanceolate, acuminate, a little shorter ; 

 lip thick and fleshy, broadly ligulate, papillose, orange-colored : column

 and slender, scarcely enlarged above the short slender base, the joints 

 (the lower 4 inches long) covered below by a close thin whitish sheath :

 flowers solitary or few, on short slender pedicels, the narrow ovary 6 

 lines long: sepals connivent, purplish, channelled, 3 lines long, the 

 lower linear-oblong, broadening upward and obliquely truncate with 

 a short lateral acumination, strongly gibbous at base, the upper linear- 

 oblanceolate ; petals apparently wanting ; lip equalling and resembling 

 the upper sepal but dilated toward the summit and broadly 3-lobed, 

 the lateral lobes very thin, pale and incurved : column narrowly mar-
