lo-bulbs ovoid, of tea much tapered to the apox, 1 to 1'25 in. long.
Leaves thiu, in paii-s on the young pseudo-bulbs, deciduous after flowering time, iiar*
rowly oblong or oblong-lanceolato, the apex acute, the base narrowed, sessile; length
3"5 to 5 ia., breadth 1 to I'-l in. Scape with an ei'ect peduncle, 3 to 5 ia. long,
sheathed at the base, and with two or tliree distant sheathing bracts; raceme drooping,
from 2 to 4 in. long, many-flowereJ. Flowers about -75 in. long, drooping, imbricate;
floral bract ovate, acuminate, 3 nerved, longer than the shortly stalked thick
ovary. Dorsal sepal ovate-oblong, sub-acute, depressed; the lateral pair less than
twice as long as the dorsal, diincHately ovate-hinceolato, cohering from base to apex.
Petals sub-orbicular, the edges with a dense belt of short purple gland-like hairs. Lip
longer than the petals but shorter than the dorsal sepal, fleshy, entire, oblong, blunt;
the edges of tiie grooved lower half up-turned. Column with large broadly falcate
hooked (inverted hatchet-shaped) apical processes, the foot short. Anther helmet-shaped,
papillose; pollinia very unequal, the outer two narrowly reniform. Hook. fil. FI. Br.

The sepals of this are of a dull yellowish green colour, changing to palo warm
brown at maturity; the floral bract is straw-colom-ed, and the rest of the flower more
or less purple with white blotches. In general appearance and coespitose habit it
resembles C. rcfractum, having like it leaves in pairs, drooping racemes and dull grcoiiishyellow
sepals. But the long upper sepal (more than half as long as the lateral pair)
suggests 8ulb->phi/lium, from which genus Cirrhopelaluvi is separated by only arbitrary
and not very constant charactcrs.

crowded. Uavcs two from the apex of a pseudo-bulb, deciduous at flowering-time, nairowly
oblong, acute, contracted at the base, sessile, 3 to 5 in. long and '7 to -85 in. broad.
Scapes 4 to 6 in. long; tlie pcduiicle erect or slightly docurvod, slender, sheathed at the
base and with two ovate-acuminate bracts; tlie raceme drooping, 1-5 to 3-5 in. long,
4- to 12-flowered; floral bract ovate-acuminate, several times longer than the short subsessile
Qvary. Flowers 1-75 to 2-5 in. long, decurved. Dorsal sepd free at the base from the
lateral pair, lanccolate, the apex awncd; the margins ciliate, depressed; tho lateral pair
about five or six times as long as the dorsal, linear, sub-acute, sparsely cihate, cohering
except at the base. ]?elal8 rather fleshy, ti-iangular, more densely ciliate than the dorsal
sepal and only about half as long. Up shorter than the dorsal sepal, very flesJiy,
oblong, obtuse; the lower surface convex, the upper smooth, deflexed from below the
middle, tho basal half with its edges iipturned, the anterior half with tufts of purple
glandular hairs, and also with long solitary hairs. Column short, with decurved slender
apical tooth, the foot short and littlo curvcd, abruptly contracted about the middle. Anther

Sikkim; at altitudes of 4,000 to 6,000 feet; common ; Pantling, No. 24; in flower
during October and November. Westward to Kamaon; also in Bm-ma and Java.
A cm-ious plant with a very wide geographical distribution. The lateral sepals, which
form by far the' largest part of the flower, are pale green when young, but change to
a pale warm brown with age. The dorsal sepal, petals and lip ai-e pale yellow, much
spotted with puj-ple, and with thick purple haii-s. The flowers have a pleasant but
faint smell of hay.
