paniculata, ramis arcuatis. Sepala lateralia oblique oblan- 
ceolata, acuta, concava. Sepalum dorsale cuneato-oblanceo- 
latum. Petala angustissime spathulato-linearia. Labellum 
columnae alte adnatum; lamina trilobata, lobis lateral- 
ibus rotundato-dolabriformibus; lobus intermedius trans¬ 
verse quadratus, leviter bilobatus. 
Plant about 85 cm. tall, rising from a woody rhizome. 
Roots coarse, fibrous, flexuous, whitish, glabrous. Stem up 
to the peduncle about 68 cm. tall, entirely invested by tu¬ 
bular leaf-sheaths which waste into fibers in anthesis, sub- 
terete. Leaves numerous, lanceolate-elliptic, 10.7-18.7 cm. 
long, about 1.6-2.7 cm. wide, distichous, strongly acuminate, 
cuneate-narrowed to a subsessile clasping base, chartaceous, 
many-nerved, 4-6.4 cm. apart but much closer near the 
summit. Peduncle up to the inflorescence about 6.6 cm. 
long, entirely concealed by 3 long scarious tubular imbricat¬ 
ing sheaths. Inflorescence a very loose panicle (3 branches 
present in our specimen). Rachis arcuate, the floral branches 
fractiflex. Floral bracts minute, triangular-lanceolate. Ter¬ 
minal floriferous branch loosely 33-flowered. Flowers small. 
Sepals fleshy, spreading. Lateral sepals obliquely oblanceo- 
late, 6.1 mm. long, about 2.5 mm. wide above the middle, 
acute, concave, 5-nerved. Dorsal sepal cuneate-oblanceo- 
late, 5.9 mm. long, about 2.1 mm. wide across the anterior 
part, acute or obtuse, somewhat concave, 5-nerved. Petals 
very narrowly spatulate-linear, about 6 mm. long, .8 mm. 
wide near the summit, rounded at the apex, 1-nerved. 
Labellum adnate to the column to its apex; lamina 3-lobed, 
2.5 mm. long in the center, 5.7 mm. wide across the spread¬ 
ing side-lobes, cordate at base; lateral lobes obliquely dolabri- 
form with rounded and irregularly lobulate basal and lateral 
margins, passing to a subacute point; middle lobe trans¬ 
versely subquadrate, broadly truncated at the apex which 
is slightly retuse, about 1 mm. long, 2.5 mm. wide, the outer 
angles obtuse or extended into short lobules. Disc with a 
large central fleshy callus of 2 parts; basal portion sub¬ 
quadrate and slightly excavated; anterior part larger, lower,
