erectum. Inflorescentiae saepissime singulae vel duae, in 
apice densiflorae. Sepala lateralia ovata, obliqua, per di- 
midium basale connata. Petala transversa, inaequilobata, 
lobo anteriore minuto. Labellum trilobatum, columna con- 
spicue brevius; lobi laterales late dolabriformes; lobus in¬ 
termedins minutus, deciduus. 
Plant variable in size, 2.5-12 cm. tall to the tip of the 
erect leaf, epiphytic, caespitose. Roots fibrous, filiform, 
flexuous, glabrous. Stems 1.2-8.3 cm. high, consisting of 
4-7 internodes, entirely concealed by dark sheaths which are 
very minutely scabrous on the longitudinal nerves with in¬ 
conspicuous erect hispid mouths. Leaf solitary, elliptic or 
ovate-elliptic, up to 4.4 cm. long and 1.92 cm. wide, subacute 
^ith a bluntly tridenticulate tip, cuneate-narrowed to a very 
shortly petioled base, coriaceous, light green. Inflorescences 
commonly 1-2 (occasionally 4 or 5 peduncles are present), 
about one-half to three-quarters the length of the erect leaf, 
filiform, densely few- to many-flowered at the apex. Floral 
tracts shallowly infundibuliform, pubescent on the outer 
surface. Flowers small, membranaceous. Lateral sepals 
obliquely ovate or lanceolate-ovate, lower half connate, up 
to 4.9 mm. long and 2.5 mm. wide at base of free portion, 
acute or acuminate with more or less outcurving tips, 
2-nerved, the longer inner nerve dorsally carinate. Dorsal 
sepal ovate or lanceolate-ovate, up to 4.9 mm. long and 3.1 
mm. wide, acute, 3-nerved with the mid-nerve prominently 
carinate on the outer surface. Petals transversely lanceo¬ 
late in outline, 2-lobed; posterior lobe relatively large, fal¬ 
cate-lanceolate or oblong, about 3.4 mm. long or less, 
broadly obtuse, more or less round-dilated at base on the 
inner margin; anterior lobe minute, triangular or ovate, 
more or less falcate, up to 1 mm. long. Labellum 3-lobed, 
shorter than the column; lateral lobes relatively large, 
broadly dolabriform with the curving sides peltate, 1.9 mm. 
ivide or less measuring along the side, apex incurved; middle
