6 ORCHIDS OF THE SIKKIM-HIMALAYA. 
Near the base of the Sikkim-Himalaya, at Salgurra, near Siliguri; elevation 
900 feet; Pantling No. 499; only once collected; in flower in February. 
The sepals and petals are of a pale reddish-brown, the lip being of a much darker 
shade of the same colour. In its thick fleshy terete rachis this species resembles 
О. pachyrachis, Reichb. fil.; and 0. orbiculuris, Hook. fil; but it differs from both in 
having the inflorescence quite free from any leaf, whereas in both these the peduncle 
of the inflorescence is adnate to a leaf. Moreover, in both these species, the flowers 
are sunk in pits in the rachis; in this they are quite superficial. The leaves in this 
are also much shorter and more fleshy. The flowers of this are very like those of 
О, orbicularis as figured by Sir Joseph Hooker (Ann. Bot. Gard. Cale. V, t. 1); 
but, in that species, the lip has no side lobes and is entire; or, if in the least 
degree erose, it is so at the apex and not at the sides or base; whereas in this 
there are three lobes, and the apical one is quite entire, while the lateral lobes are very 
erose. From the flowers of this, those of 0. pachyphylla differ in having much 
narrower petals and also somewhat narrower sepals. 
Ртлтв 4.—Oberonia pachyphylla, King and Pantling. Two plants; of natural size. Fig. 1 flower, 
front view, 2 floral bract, 3 anther, 4 pollinia; all enlarged. 
5. OBERONIA EMARGINATA, new species. 
Stems slightly exceeding an inch in length. Leaves linear, faleate, sub-acute, length 
"85 to 1:35 in., breadth *1 to 715 in. Pedunele short, with many minute linear bracts; 
raceme about twice as long as the leaves, decurved, densely-flowered for five-sixths of 
its length, but laxly-flowered in the apical sixth. Flowers very minute (less than “02 
in. long), verticillate; floral bract ovate-lanceolate, with a broad base and acute apex, 
entire, longer than the ovary. Sepals and petals sub-equal, spreading, broadly ovate, 
acute, slightly narrowed to the base, the margins entire. Гір about equal in length 
to the sepals and petals, but broader, sub-orbicular in general outline, with a shallow 
depression at the base below the column, 3-lobed; the basal lobes small, rounded, entire; | 
the terminal lobe large, with lobulate erose edges, the apex bifid, the sinus triangular. 
Anther transversely elliptic, pollinia ovoid. 
Sikkim, at Namgah, elevation 6,000 feet; Pantling No. 423; in flower during 
September. : 
| This species is allied to 0. micrantha, King.and Pantling, from which it differs in 
being caulescent, in having faleate leaves, and in having the floral braet entire and 
broader. The terminal lobe of the lip is moreover different in shape, and the sepals 
are smooth on the outer surface instead of being papillose as they are in 0. micrantha. 
Prats 2A.—Oberonia emarginata, King and Pantling. Three plants; of natural size, Fig. 1 a 
flower, seen from the front, 2 floral bract, spread out, 8 anther, 4 pollinia; aM enlarged. |. 
6. OBERONIA MICRANTHA, new species. | 
Stems very short. Leaves linear-ensiform, sub-acute, not falcate, length :35 = 1:85 in., 
breadth "1 to -2 in. Inflorescence erect, longer than the leaves, slender, terete; the 
peduncle very short, bracteolate; the flowering-rachis four times as long as the peduncle; 
floral bract. lanceolate, sub-acute, slightly erose, equal in length to or slightly exceeding
