366 ILLUSTRATIONS OF THE BOTANY OF [ Orchidece. 
elevations in the Andes, as species of Mavillaria, at 7,000 and 8,000 feet in the 
Andes of Popayan, and Oncidium nubigenum as high as 14,000 feet in the Andes of 
Peru. 
The genera, some consisting of only single species, which are peculiar to Nepal, 
are, Cremastra, Sunipia, and Cryptochilus ; Tetrapeltis and Chilochista are found in 
Nepal and Silhet ; Camarotis and Micropera in Silhet only ; Diplacentrum, in Hb. 
Heyne, therefore probably a plant of the peninsula of India; Acanthophippium in 
Silhet and Java; Cleisostoma in the latter and Ceylon. 
Geodorum is a genus common to New Holland and the southern parts of India and 
Japan. G. dilatatum is found in the latter, as well as in Silhet. Eulophia and Cyrto- 
pera, nearly allied genera, are also widely diffused, both being found at the Cape of 
Good Hope and in Madagasear ; the latter also in Sierra Leone, and the former in the 
West Indies and Peru. Though containing but few species, both are widely diffused 
over India. Cyptopera flava extends from the Morung Hills to Deokhutal on the 
banks of the Tonse, within the Himalayas; and C. obtusa, a new species, Tab. 87. 
fig. 1. is found in the valleys of Mussooree, Shalma, and Surkunda, about the same 
— latitude. So, Eulophia extends from the southern to the northern parts of India, 
E. herbacea being found in Ceylon, and as far north as the valleys of the Girie and 
Agurwal, in 80° of N. latitude. £. campestris, found by Dr.Wallich near Bhurtapore, 
in Oude, I found in arid situations in the Kheree jungles, and in the ascent to Urukta. 
E. vera, nob., is a new species found still: further north near the banks of the J hilum, 
and not far from the road which leads from N. India to Cashmere. 
Other genera, more numerous in species, which extend from the Indian Archipelago 
along the Malayan Peninsula to Silhet and Nepal, are, Vanda, Saccolabium, Podochilus, 
fErides, and Calanthe. Of these, Vanda and Afrides occur also in China; and one 
species, V. multiflora, is likewise common to both: so is, also, . odoratum, which 
spreads from Nepal to Chittagong, and thence along the Malayan Peninsula to Cochin- 
China; . affine, a Silhet and Nepal species, spreads even to30° N. along the valleys 
of the Himalaya. Saccolabium has one species, S. guitatum, spreading equally far 
north, as it grows on trees in the Kheree Pass and Deyra Doon; and is also found in 
Nepal, Silhet, Malabar, and Java. A few species occur in Madagascar, as well as 
with Calanthe in the Mauritius. S. guttatum, curvifolium, and papillosum, are common 
to the Peninsula and Nepal, as is Calanthe masuca to the latter and Ceylon. Calanthe 
extends as far north, but to much greater elevations; C. plantaginea, a Silhetand 
Nepal species, being found as high as Mussooree in flower in April ; and C. tricarinata,
