obtectus. Vaginae complanatae, valde imbricantes, margine atro 

 conspicuo praeditae. Folia disticha, oblonga, apice late rotun- 

 data et oblique bilobata, basi complicata. Inflorescentia termi-

 Sepala lateralia lanceolato-ovata, cymbiformia, valde carinata, 

 complicato-mucronata. Sepalum dorsale oblongo-ovatum, apice 

 late rotundatum, plus minusve mucronatuin. Petala anguste 

 linearia, apice late rotundata. Labellum in visu obovoideo-glo- 

 bosum marginibus incurvis , callo transverso sub medio constric-

 ovoideo-pyriformia. 



Plant small. Stem erect from a decumbent base, about 13.5 cm. 

 in height, entirely invested by closely imbricating leaf sheaths, 

 the sheathed stem clavate in outline. Leaf sheaths laterally 

 flattened, striate-nervose, furnished with a dark scarious border 

 about 1 mm. wide. Leaves up to 6.2 cm. long, 1.4 cm. wide, 

 distichous, oblong, broadly obtuse at the apex with rounded 

 oblique lobules, complicate at the sessile base, coriaceous, rigid, 

 spreading, mid-nerve sulcate above and sharply carinate beneath. 

 Inflorescence a terminal nodding hemispherical or subglobose 

 head, about 2.3 cm. in diameter in the dried specimen, con- 

 sisting of racemes. Racemes two-flowered, about 1 cm. long, 

 invested by imbricating sheaths. Sheaths about 5 mm. long, 

 tubular-involute in natural position, suborbicular when spread 

 out, pellucid, nervose. Flowers very small. Lateral sepals about 

 3.8 mm. long, 2 mm. broad, lance-ovate, strongly carinate, com- 

 plicate-mucronate, cymbiform, saccate at base, slightly oblique. 

 Dorsal sepal about 3.6 mm. long, 1.75 mm. broad, oblong-ovate, 

 broadly rounded and more or less mucronate, concave, one- 

 nerved, subcarinate. Petals about 3.2 mm. long, .7 mm. wide at 

 the base where broadest, narrowly linear, broadly rounded at the
