nov. 
Herba epiphytica, minima, repens. Radices fibrosae, 
glabrae. Caules primarii breves, repentes. Caules seecund- 
aril plusminusve erecti, apice unifoliati. Folium sessile, 
ellipticum, apice mucronatum, leviter coriaceum. Pe- 
dunculi folium superantes. Flores pauci, succedanei, in 
racemis brevibus. Sepala lateralia late obovata, acumin- 
ata, fere usque ad basim libera, uninervia. Sepalum 
dorsale simile. Petala elliptica, aliquid obtusa, sepalis 
crassiora. Labellum lanceolato-acuminatum, carnosum, 
‘arnoso cum apice inflexo. Columna supra dilatata, grand- 
ibus cum stelidiis lateralibus. Stigmata in columnae 
brachiis lateralibus infra rostellum confluentia. Flos om- 
nino subviridi-flavidus. 
Plant epiphytic, very small, repent. Roots fibrous, 
smooth. Primary stems abbreviated, repent. Secondary 
stems more or less erect, 2 mm. or less in length, each 
loosely invested by two hyaline sheaths, monophyllous 
at their apex. Leaf sessile, 6-9 mm. long, 2.5-8.5 mm. 
wide at the middle, elliptic, strongly mucronate at the 
apex, somewhat coriaceous. Peduncles conspicuously 
overtopping the leaves, up to 15 mm. long, with several 
closely appressed tubular bracts, one at the base, one 
near the middle. Flowers borne in succession on an ab- 
breviated raceme. Raceme up to 5-flowered. Rachis 1-3 
mm. long. Bracts of raceme subequal to or shorter than 
the pedicels, scarious. Pedicels (without ovary) less than 
1 mm. long. Lateral sepals broadly obovate, long-acumi- 
inate, 1 mm. long, 0.75 mm. wide, free almost to the 
base, 1-nerved. Dorsal sepal similar, 1 mm. long, 0.75 
mm. wide or less. Petals elliptical, somewhat obtuse, 1 
mm. long, 0.5 mm. wide, fleshy, with an inflexed tip. 
Lip lanceolate-acuminate, fleshy, with an inflexed tip, 
about 1 mm. long, 0.5 mm. wide. Column dilated up-
