NEW OR NOTEWORTHY ORCHIDS 
Plant closely simulating Ornithidium anceps Reichb. f., 
epiphytic, caulescent, arcuate or flexuous, commonly loosely 
branching. Roots fibrous, filiform, glabrous. Stems slightly 
compressed, entirely invested by sheaths which are closely 
imbricating, appressed, ancipitous, triangular, acute. Pseudo¬ 
bulbs cylindric, ancipitous or strongly complanate, mono- 
phyllous, about 1-5 (commonly 3-4) cm. long, .5-7.5 cm. 
distant, invested at base by distichous imbricating sheaths, 
more or less oblique and longitudinally striate in the dried 
specimen. Leaves ligulate to lanceolate-oblong, shortly 
petioled; lamina up to 20.9 cm. long and 1.9 cm. wide (rarely 
they diminish to a size of 2.5 cm. long and 7 mm. wide), 
acute, cuneate or slightly rounded at base, chartaceous in 
the dried plant with the mid-nerve more or less sulcate above 
and sharply carinate beneath; petiole short, conduplicate, 
2- 10 mm. long. Peduncles crowded in dense glomerules at 
the base of the upper pseudobulbs, very short, 1-flowered, 
invested by loose scarious imbricating sheaths. Flowers 
very small. Lateral sepals obliquely ovate, 4-4.9 mm. long, 
acute, mucronate with a dorsal keel at the tip, 5-nerved, 
anterior margins connate near the base. Dorsal sepal ovate- 
elliptic or ovate-oblong, 4.3-5.2 mm. long, concave, acute 
with a dorsal subapical keel, 5-nerved. Petals ovate-oblong 
or oblong-lanceolate, more or less constricted beyond the 
middle on one or both sides, 3.6-4.2 mm. long, acute or ob¬ 
tuse, often with a prominent dorsal thickening at the apex, 
3- nerved. Labellum continuous with the column-foot, up- 
curved and parallel to the column in natural position; lam¬ 
ina rhombic-ovate, 2-2.3 mm. long, 3-lobed below the mid¬ 
dle, rounded or subcordate at base; lateral lobes small, 
semiobovate, incurved, their apices connected by a fleshy 
transverse semilunate ridge; anterior lobe triangular-ovate, 
fleshy, obtuse. Column very short, stout, 1.25-1.75 mm. 
long at the back, extended into a stout very fleshy upcurved 
foot which is subequally long, gradually dilated above, 
abruptly 3-lobulate at the apex with the central tooth gently 
retuse. Pollinia 4, pyriform. Stipe linear.
