pars terminalis rhombico-lunata, apice rotundato apicu- 
lata. Calcar filiformi-cylindraceum. 
Plant terrestrial from a decumbent rooting base. Roots 
simple, fibrous, lanuginose, apparently verticillate in 
twos, threes or fours. Stem slender, suberect, glabrous, 
leafy, about 26.5 cm. high from the tip of the spike to 
the rooting portion. Leaves about ten, petioled; blades 
elliptic to lanceolate, acute or acuminate, broadly cuneate 
at base, up to 11 cm. long and 8.6 cm. wide, with three 
to five rather prominent nerves; petioles channelled, di- 
lated into a loose scarious infundibuliform sheath sur- 
rounding the stem, up to 2.8 em. long. Peduncle short, 
wholly concealed by loose imbricating sheaths. Spike 
short, exceeded by some of the upper leaves, densely 
many-flowered, apparently quaquaversal, about 5 em. 
long (the upper flowers small and immature), and up to 
3 cm. in diameter in the dried specimen. Ovary slender- 
cylindric, very sparingly pilose. Flowers small, glabrous, 
spreading; segments little spreading. Dorsal sepal ob- 
lanceolate-oblong or lanceolate-elliptic, obtuse at the 
cucullate apex, concave, about 5.1 mm. long and 2-2.2 
mm. wide, 1-nerved. Lateral sepals obliquely oblong- 
oblanceolate, about 5.8-6 mm. long and 2 mm. wide, 
subacute to obtuse at the slightly cucullate apex, with 
the anterior margin long-produced and adnate to the 
spur. Petals linear-spatulate, lightly oblique, abruptly 
acute to subobtuse, I-nerved, about 5 mm. long and 
1.2-1.5 mm. wide above. Lip abruptly constricted above 
the middle with the basal portion concave and the ter- 
minal portion recurved flat and spreading, about 4.6—5 
mm. long when expanded; lower portion broadly obo- 
vate, commonly minutely angled on each side at the 
apex when spread out; terminal lobe rhombic-lunate, 
broadly rounded in front with a short apicule, narrowed 
to ashort broad claw below, about 3.6 mm. wide between
