38 THE ORCHID REVIEW. 
ORNITHIDIUM NANUM, Rolfe.—A small West Indian species which was 
sent to Kew by Mr. Wilke, of the Rotterdam Botanical Garden, and 
flowered in the collection in September last. The flowers are yellowish 
white, and not unlike those of Dendrobiut, crymenatum in shape.—Kew 
Bulletin, 1894, p. 395. 
TRICHOCENTRUM Hartu, Rolfe.—A Venezuelan species which was sent 
to Kew by J. H. Hart, Esq, F.L.S., Superintendent of the Trinidad 
Botanic Garden. It also flowered with Sir Tyeyor Lawrence in September, 
1892, having been obtained from Messrs. Linden. It is allied to T. fuscum, 
Lindl., but has a curved spur shorter thay the lip.—_Kew Bulletin, 1894,

SARCOCHILUS CRASSIFOLIUS, Rolfe.—A Species of unknown origin which 
flowered in the collection of M. A. Van Imgchoot, Gand, last October. It 
is a climbing species with flattened stem, allied to the Javan S. anceps, 
Rchb.f, and bears yellowish white flowers, with the front lobe of the lip 
yellow and an orange blotch behind the crest —Kew Bulletin, 1894, p. 396.

SACCOLABIUM x BELLINo. BIGIBBUM. 
Natural hybrids among Orchids are becoming rather numerous, and pre- 
sumably may occur wherever nearly-allied species grow intermixed. ‘Vanda 
and Catasetum have recently been added to the list of genera in which they 
occur, and now Saccolabium may also be included. In October, 1893, a 
curious little Saccolabium flowered at Glasheyin, under the charge of Mr. 
F. W. Moore, A.L.S., which had been obtained as S. yee ibbum, though in 
| 
some respects it was almost as much like S. bellinum, another eee 
species, well known in gardens. Careful COmparison revealed the fact that 
it combined the characters of both species, a, hybrids invariably do, : and on 
inquiry I learn that in Burma the two are foung together. ‘The hybrid has 
the habit and foliage almost of S. bellinum, pyt much smaller flowers—in 
fact, they are about intermediate in size beth da those of ‘the two species. 
The lip is rather small, and resembles S. bigipbum in shape rather than the 
other species. The sepals and petals are déep red-brown, yellowish at the 
extreme margin, the petals having a very Narrow yellow line in the middle. 
The lip is white, spotted with purple, the base of the sac yellow spotted with 
brown, and the column carmine. It is a Very interesting and pretty little 
plant, and its hybrid origin seems to be Pea ses proved by the facts 
above pointed out. ie oe
