Rhizome stout, wiry, "2 in. thick; pseudo-bulbs close together or '5 in. apart,
broadly ovoid, '75 to 1 in. long, and about »6 to -7 in. in diam. at the base. Leaf
4-5 to 6'5 in. long, oblong-lanceolate, acute, narrowed at the base into a channelled
petiole 1'5 to 2 in. lonsr. Scape longer than the leaf; the peduncle with 3 or
4 sheathing lanceolate bracts; the raeei7ie longer than the peduncle, incUned or dccurved,

the shortly stalked ovary. Flowers '5 in. across, opening 3 or 4 at a time, brown.
Sepals sub-equal, narrowly lanccolate, with broad concave 5-nervcd bases and caudateacuminate
apices, about -4 in. long. Pelals much smaller than the sepals, orbicular,
fleshy, the anterior half with tho margins aud apex softly bearded. Lip slightly
longer than the sepals, very mobile, lanceolate with a truncate auricled base, broadly
fimbriate-fringed except at the base. Column stout, with two elongate minutely
capitate erect teeth at the apex, and a protuberance under the stigma; its foot short
and much curved. Anther conical with a fimbriate crest; pollinia unequal. Hook fil.

Bhutan; at Song-chong-loo, elevation 6,000 feet; Pantling No. 251; flowering in
August and September.
The colom- of the sepals and petals is of a unifoi-m brown, the Hp being of a paler
tint; the rachis is also dark brown. The lower part of the raceme is occupied by
empty bracts. Except in the colour o( the flowers, this Bliutan plant agrees exactly
with the type specimens of B. Pfinieillium which were collected in Burma. Wo have no
doubt whatever, after carcful comparison of specimens of both at Kew, that the Bhutan
and Burma plants are conspeclflc. Although not strictly speaking a native of Sikkim,
this was found so near the frontier, and is such a remarkable plant, that wo have
included it in this work. The lip is so extremely mobile that it responds to the
faintest movement of the air. The nature of tho motion, which is spasmodic rather
than oscillatory, is described in the following note by Mr. Pantling: " I have recently
carefully observed the behaviour of the lip of this species, and I find that the Hp does
not oscillate, but has a jerky movement. In its normal position it is pressed to tbe
face of the column as shown in figure I. The only other position which I have
ever seen it occupy is that oE extreme depression, as depicted in fig. 4; there is no
intermediate position whatever. The raovcmeat from tho one position to the other
is sudden and spasmodic; and so extremely delicate is the balance that, even when
the air appears to be quite still, a Hp here aud there may be observed suddenly
to drop, and as suddenly to resume its normal position."
