spathulato-oblanceolata vel anguste oblanceolata. Label- 
lum simplex ; lamina columnae adnata et columnam cir- 
cumdans, late cordata, acuminata, valde concava, nervis 
conspicuis ornata, marginibus anterioribus utrinque in- 
volutis ut apex rostriformis appareat. Columna parva. 
Plant small, much branched especially above, up to 
14.5 em. tall, widely spreading, sometimes arcuate. Roots 
fibrous, flexuous, glabrous, commonly numerous, issu- 
ing from the base and lower parts of the stems. Stems 
entirely or mostly concealed by densely pustulose leaf- 
sheaths which are more or less evanescent in age. Leaves 
small, numerous, spreading, distichous, often suboppo- 
site, elliptic-oblong to linear, up to 2.1 cm. long including 
the very short petiole, up to 4.5 mm. wide (blade pre- 
served in alcohol), fleshy, commonly more or less arcuate 
and conduplicate in the dried specimen, abruptly bilobed 
at the apex with nearly equal rounded lobules. The living 
leaf-blade is apparently very fleshy, with the mid-nerve 
longitudinally suleate above so that the upper surface is 
concave and the lower surface convex. Inflorescences ter- 
minal, commonly 1-flowered (very rarely 2-flowered), 
subsessile with a very short recurved peduncle. Pedicel 
concealed by a pustulose infundibuliform bract. Perianth 
rigid-nervose, with the parts widely spreading. Dorsal 
sepal oblong or elliptic-oblong,sometimes slightly broad- 
er above the middle, about 8-10.5 mm. long and 2-2.6 
mm. wide, acute or dorsally mucronate at the apex, 7- 
to 1l-nerved below the middle. Lateral sepals elliptic- 
oblong or oblong-lanceolate, slightly asymmetric, about 
8-10 mm. long and 2.5-2.9 mm. wide, dorsally mucronate 
at the apex, 7- to 11l-nerved below the middle. Petals 
spatulate-oblanceolate or narrowly oblanceolate,7—9 mm. 
long, 2-2.7 mm. wide above the middle, acute or sub- 
acute, 3-nerved to near the apex or 5-nerved below the 
middle, sometimes minutely bulbose-thickened at the
