dato apiculatum, quinquenervium. Sepala lateralia lan- 
ceolato-oblonga, acuta, leviter obliqua, trinervia. Petala 
sepalis multo breviora, elliptico-obovata, apice rotundata, 
trinervia. Labellum quam petala brevius, leviter triloba- 
tum, apice rotundatum, cum lobulis lateralibus semiobo- 
vatis et incurvis. Columna abbreviata, breviter pedata. 
Plant robust, probably caespitose (base of stem and 
rhizome not present). Stem stout, up to 15.5 cm. high, 
provided with two or three loose tubular scarious sheaths; 
uppermost sheath separate, much the largest, up to 7.5 
em. long. Leaf oblong-elliptic to oval (often slightly 
broader above the middle), sessile or subsessile, 11.4—-15.5 
em. long, 4.7-7.5 cm. across, broadly rounded and slight- 
ly retuse at the apex, cuneate below, thickly coriaceous 
in the dried specimen, many-nerved with the mid-nerve 
suleate above and prominently carinate beneath. Ra- 
cemes four to six, erect or suberect, densely many-flow- 
ered, apparently secund, up to 19 em. long, shorter than 
or slightly surpassing the leaf, issuing from a prominent 
conduplicate shining spathe which is up to 4.2 em. long. 
Floral bracts short, infundibuliform. Flowers small for 
the plant, campanulate with but slightly spreading seg- 
ments. Sepals subfleshy, closely pubescent within except 
near the base, lightly carinate without. Dorsal sepal 
slightly adnate to the lateral sepals at the base, strongly 
concave below, ovate-oblong, 9.5-10 mm. long, 4.8—5 
mm. wide, abruptly rounded and apiculate at the apex, 
5-nerved. Lateral sepals lanceolate-oblong, acute, con- 
cave below, slightly oblique, 9-9.5 mm. long, about 3.2 
mm. wide, 3-nerved (sometimes with a short supplemen- 
tary nerve), more or less connate near the base. Petals 
much smaller than the sepals, elliptic-obovate, 4—4.5 mm. 
long, 2.2-2.7 mm. wide, rounded at the apex, 3-nerved. 
Lip smaller than the petals, fleshy, lightly 3-lobed, 3- 
nerved, slightly arcuate in natural position with concave
