lus uniflorus, dense albo-lanatus. Sepala lateralia lineari-oblonga, 

 late obtusa, basi mentum saccatum formantia. Sepalum dorsale 

 persimile. Petala linearia, obtusa vel subacuta. Labellum in cir- 

 cuitu anguste lanceolatum, trilobatum; lobi laterales leviter tri- 

 angulares, obtusi, patentissimi ; lobus medius subito oblongo- 

 linearis, apice rotundato, parte anteriore valde incrassata. Gyno-

 uneiformi praeditum. 



Plant small. Roots very numerous, intertwining, branching, 

 fibrous, closely spreading pubescent, up to .5 mm. thick. Stems 

 approximate, up to 3.35 cm. high, 2 mm. thick, monophyllous, 

 entirely concealed and much surpassed by several imbricating 

 sheaths. Sheaths ±4 cm. long, deltoid to narrowly lanceolate, 

 long acuminate, scarious, loose, nervose, the mid-nerve dorsally 

 carinate, becoming fibrous. Leaf ±10.5 cm. long, 1 cm. broad, 

 narrowly oblong or linear, very obliquely and obscurely bilobed 

 at the apex, narrowed to a sulcate petiole ± 1 cm. long, thick and 

 coriaceous, rigid, with the mid-nerve more or less sulcate above 

 and carinate beneath, margins more or less revolute in the dried 

 plant. Peduncle about 3 cm. long, one-flowered, slender, one 

 or two to each stem, rising within the base of a sheath from the 

 side of the stem, shorter than or surpassing the sheaths, densely 

 white lanate. Flower about 1.4 cm. long with segments conni- 

 vent in natural position. Ovary about 9 mm. long, densely white 

 lanate. Sepals densely white lanate without. Lateral sepals about 

 11.5 mm. long, 3.5-4 mm. wide, linear-oblong, obtuse, somewhat 

 thickened at the apex, five-nerved, very oblique at the base 

 and forming a saccate mentum. Dorsal sepal very similar. Petals 

 about 1 cm. long, 2 mm. wide, linear, slightly falcate toward 

 the dorsal sepal, obtuse or subacute, slightly thickened at the 

 apex, three-nerved. Lip in outline lanceolate, three-lobed, about
