Sikkim, at Choongthang, elevation 6,000 feet ; in flower during May; Pantling,
No. 365,
This species comes neai-est to C. Mannii, Hook, fib, which has, however, a very
short spur. This is as yet a little-known plant, only a few specimens having hitherto
been gathered. The flowers are swcet-sconted. The lip is of a bright yellow and the
column is nearly white, the other parts "of tho flower being yellowish-green. We
have named it after Jlr. Claude "White, Political Ageut ia Sikkim, who has given us
much help in obtaining botanical specimens from Independent Sikkim.

15. CALAKTUE DENSIFLORA, Lindl. in Wall Cat,, 7344; Gen. and Spec.
Orch., 250.
Rhüome consisting of joiuted fusiform annular lengths about 9 in. long, each
producing at its thick end a pseudo-stem and flowering scape. St:m very short. Leaves
about three, nai-rowly elliptic, acutc, tapering at the base to the short broad sheathing
petiole ; length 2 to 3 feet, breadth 3 to 6 iu., petiole 2 to G in., sometimes absent.
Scape from the rhizome behind tho stem, 4 to 12 in. long, erect, stout, bearing throe or
four broad tubular acute inflated sheaths 1 in. or moro in length. liaceme 2'5 to 3 in.
long, at first sub-globose, afterwards cylindrical, densely-flowered, sometimes branching-
Flowe/ (to the end of the spur) '8 in. long, and in diam. -5 in.; liracf thin, elliptic, acute,
condupHcato, longer than the abruptly stalked ovary, the hraeis of the lowest flowers often
much longer. Spw nearly aa long as the ovary and its pedicel, cylindric, slightly
inflated towards the apex. Sepals and petals connivent, sub-equal, oblanceolato, acute.
Lip adnate to the column from its middle ; the basal lobes large, sub-triangulor, erect,
and with two large semi-erect rounded lamellfe between them; apical lobe quadrate,

emarginate, the sinus broad, shallow. Column straight, thick at the base only, shorter
than tho spur. Sligma rounded, entire. Anther witli a short oblong transparent lip.
Pollinia sub-equal, globose-clavate, attached by a single caudicle to a small gland. Lindl.

Bhutan, in the Naru Valley, at an elevation of 3,000 feet ; in flower during
October; Pantling, No. 351; collected also by Treutler and others. Khasia Hills; alt.
4,000 to 5,000 feet.
The flowers are yellow throughout. Prior to their expansion the raceme is covered
by thin deciduous bracts. We can find no difference between this and C. clavaia,
Lindl., and have therefore reduced the latter, as being described by Lindley on a later
page of his genera and spccies of Orchids.

33. Yoania, Maximowicz.
Saprophytic aphyllous succulent herbs with stout branched rootless rhizomes. Slem
2 to 4 ill. high, erect, stout, bearing a few short fleshy Iraeis and, at its apex, four
or five loug-stalkod flowers nearly 1 in. long in a short lax raceme. Sepals and petals
short, concave, the former fleshy. Lip about as long as the sepals and petals, sessile
on the short foot of the column, somewhat siippcr-shaped, the margins of tho anterior
half approximated so as to convcrt the posterior half into an open sac; spurred or not.
Stigmz transverse, concave. Column stout, broad, with a tooth at the apox on each side
of the author, the margin winged. Pollinia 2, bi-partite, waxy, sessile on a large quadrate
gland resembling that of Cymhidiim, Distrib., two species, Japanese and Indian.

length from 1 to 2 in. Sepals o vate-lanceolate, sub-acute. Petals of thinner texture than
the sepals, ovate-rotund, very obtuse, entire, and with five parallel non-converging nerves.
Lip with entire edges, not spurred. Anther anticous, broad, dome-shaped, beakod.

This spocics differs from Y. japónica of Slaximowicz, as originally described by that
author in the Bulletin of the St. Petersburg Academy (Vol. XVIII, p. 68), and more
recently described and figured by M. Finet in the Bulletin Soc. Bot. de France,
Vol. XIV, 601, t. XII. In tho present species the lip has entire edges; it has no
spur and no processes on any part of its upper surface; in Y. japónica tlie edges
of the lip are serrate, and there is curious blunt spur dh'ected forwards and bearing
