emarginate, the sinus broad, shallow. Column straight, thick at the base only, shorter 
than the spur. Stigma rounded, entire, Anther with 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. clavata, 
Lindl., and have therefore reduced the latter, as being described by Lindley on a later 
page of his genera and species of Orchids.

Saprophytic aphyllous succulent herbs with stout branched rootless rhizomes. Stem 
д to 4 in, high, erect, stout, bearing a few short fleshy bracts and, at its apex, four 
or five long-stalked flowers nearly 1 in. long in a short lax raceme. Sepals and petals 
short, concave, the former fleshy. ip about as long ав the sepals and petals, sessile 
on the short foot of the column, somewhat slipper-shaped, the margins of the anterior 
half approximated so as to convert the posterior half into an open sac; spurred or not. 
Stigma transverse, concave. Column stout, broad, with a tooth at the apex on each side 
of the anther, the margin winged. Pollinia 2, bi-partite, waxy, sessile оп a large quadrate 
gland resembling that of Cymbidium, Distrib., two species, Japanese and Indian. 
YoawrA Рвлткп, new species, 
Роты densely clothed with iced imbricating narrowly lanceolate acuminate 
adpressed scales. Stem smooth; its two or three bracts -4 to “б in. long, loose. Flowers 
about 1 in. long; floral bract “5 in. long, ovate, fleshy, the ovary and its stalk varying in 
length from 1 to 2 in. Sepals ovate-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, beaked. 
Capsule 2 to 2:5 in. long, narrowly fusiform, boldly ridged, erect, on a stout stalk.

Sikkim-Himalaya, at Choongthang, elevation 6,000 feet; Pantling, No. 469. Naga 
Hills; elevation about 7,000 feet, Prain, No. 15. 
This species differs from У. japonica of Maximowicz, as originally described by that 
anthor in the Bulletin of the St. Petersburg Academy. (Vol. XVIII, p. 68), and more 
recently described and figured by М. Finet in the Bulletin Soc. Bot. de France, 
Ver XIV, 601, €. XII. In the present species the lip has entire edges; it has no 
spur and no processes on any part of its upper surface; in У. Japonica the edges 
of the lip are serrate, and there is curious blunt spur directed forwards and bearing
