Rhizoma repens. Caules secundarii valde abbreviati, 
monophylli. Folium ellipticum vel orbiculare, integerri- 
mum, marginatum. Pedunculus elongatus, glaber, folio 
multo longior, prope apicem pauciflorus. Sepala lateralia 
in laminam orbicularem apice bidentatam cohaerentia. 
Sepalum dorsale valde concaviusculum, oblongum, ob- 
tusum, trinervium,. Petala lanceolata, obtusa, margine 
glandulosa, uninervia. Labellum linguiforme, basi auric- 
ulatum, margine supra medium longe pilosum. Colum- 
na apice irregulariter fimbriata. 
Rhizome branching, creeping, monophyllous at the 
nodes, each leaf subtended by an abbreviated root. Sec- 
ondary stems up to 1 mm. long, rigid. Leaves about 3 
mm. apart, up to 6 mm. long, 8-8.5 mm. wide, elliptic 
or lenticular, entire, conspicuously marginate, fleshy. 
Peduncles about 6 mm. long, borne singly in the axils 
of the leaves, with a tubular bract at the base, otherwise 
naked below the lowermost flower, glabrous. Flowers 
about four, opening in succession, 2 mm. long. Lateral 
sepals 2 mm. long, coherent almost to the tip, forming an 
orbicular lamina 1.5 mm. wide, strongly concave at the 
base, smooth. Dorsal sepal 2 mm. long, strongly concave, 
about 0.5 mm. wide, oblong, obtuse, 8-nerved. Petals 
about 2 mm. long, hardly 1 mm. wide, lanceolate, ob-
