ob'.ong. somDwhat falcate, sub-acute, connate with each other at the base and with the
sac o£ tho lip. Petals about as large as tho dorsal sepal, falcately oblanceolato, bluntly
acuminate. Lip with a rather long oblong liorizoutal sac or spur at the base decurrent
on the ovary; the claw long and with distant and unequal teeth on each side; apical
lobe with two oblong diverging lobules with truncate erose apices; the sinus very wide
and with a miuuto apLculus at its apex; the sac with a lateral sub-quadrate apiculate
callus on each side in its interior. Cjlumti short, with two narrow appendages; rostcllum
large, broad, bifid. Anther much pointed; polUnia clavate, compressed, tho apices
emarginate, united below and joined directly to the small gland by a long psoudocaudicle.

Sikkim, at elevations of from 4,000 to 6,000 feet; Hooker; at Tendong, Pantliag
No. 325; in flower dm-iug July. Khasia lliils; Hooker and Thomson.
The sepals and petals are pale groen, mottled with white and tipped with pink.
The lip is wliite, the teeth of the claw being green and the sac being flushed with
yellow; the column is green below and pink above. The leaves on both surfaces are
pure green. The flowers at the middle of the raceme are occasionally the first to open,
expansion proceeding upwards and downwards simultaneously as showa ia the plate.

5. Ancectochilus Eiavesif, King and Pantling.
"Whole plant 8 to 10 in. high. Stem rather stout, decumbent at the base,
glabrous. Leaves six or seven, ovate, acute, narrowed at the base, 3-nerved, the
margins hyaline, length l'2-3 to 1-75 in.; petiole about -5 ia., expanded at the bass.
Peduncle shorter than the stem, clothed with long soft glandular hairs and bearing
Rcvoi-al lanceolate acuminate bracts. Raemn shorter than the peduncle and, like
it and the floral bracts and oviiries, glandular-hairy. Flowers two or three, about
1 in. long; floral bract lanceolate, as long as the ovary. S^pah unequal, tho dorsal
ovate-cordate, sub-acute; the lateral pair much larger, broadly oblong, sub-falcate,
blunt, diverging. Petak broadly oblong, falcate, acute, about as long as the dorsil
biit much shorter than the lataral sjpa's, l-nerved, aad with a few long hairs outside.
The basal sac of tho lip shallow, s!iortly bifid, and containing witliin it two cojicai

calli; tho claw uan-ow and bearing about six pairs of coarse teeth on each side;
tho apical lobo divided by a broad deep sinus into two diverging obliquely-oblong
or sub-quadrato truncate undulate lobules. Colunvi stout with two parallel appendages
in tho neck of the spm-. Anther beaked; polUnia ob'iquo, unequal, clavate but flattened,
pscudo-caudiclo short; gland situated on one side of tho twisted beak of tho anther.

to 0,000 feet; Clarke, King, Pantling iio. 224; in flower during Jiily and August.
Khasia Hills, at Shillong; Clarke. Naga Hills, at Kohima; Prain No. 17.
There is some variation in tho coloming of the floAvors and leaves of this
species. The common form in Sikkim has the sepals green witli white midribs and
biowii tips, and the petals white, also tipped with brown. Tho lip is white, but tho
teeth of the claw are brown and tlie basal sac is green. Tho leaves are of a
uniform brown, as also is tho axis. Dr. Prain, who made careful notes on the plant
as it grows at Kohima in the Naga Hills, describes the sepals as coloured like those
of the Sikkim plant; the petals being gi-een and tlie claw of lip yellow for tlio
most part, but having a red central line and its teeth beuig greenish-yellow, tho
apical lobules being white. The leaves ho describes as olive green on the upper
sm-face and coppery on tho lower.
Pr-.\TE ZM.—Aws-.tochUm E'tosni, King and Pantliag. A plant, of natural size. Fig. 1 the sepals
and petals separated, 2 the lip with its sao and the apes of the ovary and column, seen from above,

6. Ascectochilus CRisrus, Lindl. in Jom-n. Linn. Soc. I, 180.
"Wliolo plant 5 to 8 inches high. Stem decumbent at the base, slender. Leaves
few, ovate, acute, the edges minutely undulate, length -5 to •75 in.; petiole -35 to -05
in loiig, dilated at the base. Peduncle much short or than the stem, pubescent and
with one or two pubescent lanceolate sheaths with acuminate apices and tubular bases.
Spi/ce 4- to 8-flowcred. Flowers -7 in. long; floral bract pubescent, lanceolate, about as
long as tho glabrous ovary. Sepals unequal, pubescent; the dorsal convex, its apex
upturned; the lateral pair longer, spreading, oblong, witli obliquely sub-acute apiccs.
Petals triangular-falcate, conniving under the dorsal sepal. Lip deflexed from the base
with a small globular sac at the base connected with the apical lobe by a long narrow
untoothed claw; the apical lobe sub-rotund, divided by a shallow sinus into two broad
lobiilos, the edges imdulato and minutely crcnulate or dentate, the iaiterior of the sac with
two large sub-quadi'ate erose lamcllaj. Column and rostellar arms shoit. Anther broad,
with a narrow pointed beak; pollinia sub-globose; tho pseudo-caiidicle large, broad, and
composed of cohoiing imbricating scales without elastic threads; gland small, quadrate.
