to subacute and tridenticulate at the apex, tapering at 
the base into the short petiole, marginate, fleshy, gla- 
brous, somewhat undulate-contracted on the margins and 
conduplicate-ensiform with age, up to 13 mm. long in- 
cluding the petiole and 5.5 mm. wide. Inflorescences 
one or two, commonly a little shorter than the leaf, loose- 
ly 8- to 8-flowered. Floral bracts ovate-cucullate, acute, 
glabrous, less than 1 mm. long, longer than the pedicel- 
late ovaries. Flowers extremely small, somewhat arcuate- 
recurved, about 8 mm. long. Sepals pale yellowish green, 
united at the base. Dorsal sepal elliptic-lanceolate, acute, 
concave below the middle, 3-nerved, up to 8 mm. long 
and 1.5 mm. wide near the base. Lateral sepals united 
to about the middle, obliquely ovate-elliptic, acute, up 
to 2.5 mm. long and 1 mm. wide above the point of coa- 
lescence. Petals green and reddish purple, broadly flabel- 
liform-bilobed, with an apicule in the sinus, up to 0.5 
mm. long and 1.2 mm. wide; posterior lobe oblong- 
lanceolate, obtuse; anterior lobe obliquely quadrate, trun- 
cate or retuse at the apex. Lip bright purple, with a 
rather broad involute claw, 3-lobed, obovate in outline, 
about 1 mm. long, usually narrower than long; lateral 
lobes not auriculate at the base, linear-oblanceolate, cres- 
centiform, broadly rounded at the apex, incurved so as 
to overlap one another, lightly keeled near the middle; 
mid-lobe small, narrowly ovate-triangular, subacute, pu- 
bescent. Column cylindrical, fleshy, about 1.2 mm. long, 
with a dorsal flap near the apex, acute-apiculate at the 
apex; clinandrium tridentate; pollinia two. 
This species is easily identified by its peculiar lip which 
has rather broad lateral lobes which are incurved in front 
so as to overlap. The column and petals are also distine- 
tive and are useful in separating the species from nearly 
allied entities. The specific name signifies ‘‘overlapping”’ 
in reference to the position of the lateral lobes of the lip.
