nov. 
Herba elata, gracilis. Radices tuberosae. Folia ba- 
salia, rosulata, elliptico-oblanceolata vel oblanceolata, ad 
basim petiolatam angustata, acuta. Scapus inferne glab- 
er, superne glanduloso-pubescens. Racemus laxiflorus. 
Flores parvi. Sepala lateralia oblique ovata, obtusa. Sep- 
alum dorsale elliptico-lanceolatum, concavum. Petala 
sepalo dorsali valde adnata, obliquissime deltoideo-rhom- 
bica, basi cuneata. Labellum valde concavum, subsessile, 
apice profunde trilobatum. Columna brevis. 
Plant tall, about 40 em. high. Roots tuberous. 
Leaves basal, rosulate, five in this single specimen, el- 
liptic-oblanceolate or oblanceolate, gradually narrowed 
into a petioled base, 18 em. or less long, up to 2.9 em. 
wide, acute, membranaceous. Stem slender, provided 
with eight scarious tubular acuminate sheaths of which 
the lowermost is 1.75 cm. long, glabrous below, finely 
glandular-pubescent above. Raceme loose, exceeding 10 
em. in length (incomplete), 23-flowered or more. Floral 
bracts lanceolate, acuminate, up to 4.5 mm. long, pube- 
scent on the outer surface. Pedicellate ovary slender, 
spreading, 6 mm. or less long, glandular-pubescent. 
Flowers very small for the genus. Sepals sparsely gland- 
ular-pubescent near the base on the outer surface. Lat- 
eral sepals obliquely ovate, about 83 mm. long, up to 2 
mm. wide, obtuse. Dorsal sepal elliptic-lanceolate, about 
3 mm. long and 1 mm. wide, subacute, concave. Petals 
adnate to the dorsal sepal, obliquely deltoid-rhombic,
