foliorum haud dilatati; vaginae foliorum imbricatae, persisten- 
tes, nitidae, stramineae, prope apicem caulis haud inflatae (in 
vivo et in sicco), marginibus flavidis; nodi 1 ad 2 cm distantes. 
Folia usque ad 9 cm longa, prope basim 5 ad 6 mm lata, linearia, 
acute acuminata, ad basim torta. Inflorescentia terminalis ca- 
pitata, multiflora, 1.5 ad 2 cm in diametro. Bracteae exteriores 
inflorescentiam amplectentes, rigidae, lanceolatae, floribus lon- 
giores; bracteae florales obtusae, floribus breviores, glumaceae. 
Pedicelli cum ovario 6 ad 7 mm longi. Sepala lateralia ovato- 
lanceolata, tenuiter acuminata, obliqua, trinervia, circiter 6 mm 
longa, ad basim 3 mm lata. Sepalum dorsale simile. Petala 
lineari-laneeolata, circiter 5 mm longa, ad basim 1.5 mm lata. 
Labellum carnosum, ad basim leviter saccatum, saccus antice 
in laminam retusam productus, 7 mm longum; epichilium del- 
toideo-ovatum, circiter 5 mm longum, 4.5 mm latum, acutum, 
margine involutum, leviter apiculatum, expansum minute tri- 
lobatum. Gynostemium circiter 5 mm longum, rostellum ova- 
tum, sulcatum. Pollinia 8. 
An epiphyte; the roots very numerous, 1.5 to 2 mm in diam¬ 
eter. Stems tufted, erect, terete, slender, 21 to 40 cm long, 
2 to 2.5 mm in diameter at the base, forming large clumps up 
to 30 cm in diameter; the nodes 1 to 2 cm distant, light green 
and entirely covered by the straw-colored persistent leaf sheaths. 
The leaf sheaths not inflated above both in the living and in the 
dried specimens, the margins yellowish. Leaves restricted to 
the upper portion of the stems, distichous, the bases twisted, 
linear, acutely acuminate, up to 9 cm long, 5 to 6 mm wide at 
the base, the very apex sharply triapiculate. Inflorescences ter¬ 
minal, capitate, many-flowered, not very dense, composed of 
short spikes, 1 to 2 cm in diameter; flowers 1 to 3 on a spike, 
opening simultaneously, about 1 cm across. Peduncles about 5 
mm long. Exterior bracts sheathing the inflorescence, rigid, 
lanceolate, longer than the flowers, the floral ones glumaceous, 
obtuse, shorter than the flowers. Pedicellate ovary 6 to 7 mm 
long. Lateral sepals ovate-lanceolate, oblique, sharply and 
acutely acuminate, three-nerved, about 6 mm long, 3 mm wide 
at the base. Dorsal sepal similar to the lateral ones. Petals 
linear-lanceolate, three-nerved, acute, about 5 mm long, 1.5 mm 
wide at the base. Labellum fleshy, constricted near the middle, 
the basal part saccate, about 7 mm long; the epichile deltoid- 
ovate, acute, about 5 mm long, 4.5 mm wide, the margins in¬ 
volute, minutely trilobed at the apex when expanded. Column 
short and broad, abruptly constricted in the middle with a fleshy
