supra vaginis tubulatis ornatus. Folia oblanceolata vel 
oblongo-oblanceolata. Spica cylindrica, saepissime laxe 
multiflora. Florum bracteae ovato-lanceolatae, glabrae, 
quam flores breviores. Flores parvi. Sepalum dorsale 
elliptico-lanceolatum, columnae adnatum. Sepala later- 
alia basiin tubum brevem connata; pars libera oblongo- 
lanceolata vel lineari-oblonga, faleata. Petala oblique 
linearia, supra paulo latiora. Labellum superum, carno- 
sum, tubulari-involutum, expansumcucullato-obovatum, 
dorso dense muriculatum, marginibus eroso-denticulatis. 
Columna generis. 
Plant terrestrial, rather slender, up to about 5.1 dm. 
tall. Roots fasciculate, numerous, slender-tuberous. Stem 
glabrous, provided above the base with about four tubular- 
cylindric sheaths which are loose in the dried specimen 
and have an acute apex. Leaves four to five, crowded at 
or just above the base, oblanceolate to oblong-lanceo- 
late, acute, gradually narrowed below to a sheathing 
base, up to about 15.5 em. long (including the base) and 
2.5 em. wide, with the mid-nerve carinate beneath. 
Spike slender-eylindric, up to 12.5 em. long, subdensely 
or loosely flowered, commonly many-flowered; rachis 
more or less tomentose. Floral bracts ovate-lanceolate, 
acuminate, glabrous, scarious, surpassing the pubescent 
ovary but shorter than the flowers. Flowers small with 
erect lip and membranaceous reflexed or spreading sepals 
and petals, green throughout. Dorsal sepal elliptic-lan- 
ceolate, obtuse or subacute with a cucullate apex, adnate 
to the column at its base, about 5.2—6.2 mm. long and 
2 mm. wide, 1- or 8-nerved. Lateral sepals obliquely 
linear-oblong to oblong-lanceolate, faleate, complicate- 
acute, 1-nerved, connate into a short tube at base, the 
free portion about 6.5-7.5 mm. long and 2 mm. wide. 
Petals obliquely oblanceolate-linear, adnate to the col-
