subtending leaf or less. Floral bracts minute, loosely in- 
fundibuliform, glabrous, apparently dark reddish brown. 
Flowers very small, glabrous, yellow. Sepals membra- 
naceous, widespreading, deeply connate at the base. 
Dorsal sepal relatively large, triangular-ovate, acute or 
short-acuminate, 3-nerved, about 5 mm. long along the. 
mid-nerve and 4.4 mm. wide at the base of the free part. 
Lateral sepals obliquely triangular-ovate, acute and 
short-apiculate, with the inner margins connate through 
the lower half, 1-nerved, about 4.4 mm. long along the 
nerve and 2.5 mm. wide near the base. Petals very small, 
transversely suborbicular-oval, broadly rounded or sub- 
truncate above, about 1.2 mm. long and 2 mm. wide. 
Lip 3-lobed, attached to about the middle of the column 
by the broad base of the lateral lobes; lateral lobes do- 
labriform-peltate with linear-lanceolate pubescent outer 
surface which is about 2 mm. long and rounded at each 
end; mid-lobe minute, broadly rhombic-ovate, sharply 
bidentate, pubescent. Column slender, about 1.9 mm. 
long. 
This species appears to have no near allies.
