Ganges, and C. Wallichii in Nepal. Bolbophyllum, very numerous in species, thought 
to be confined to Africa and Asia, has also been found in Demerara, and extends east to 
China, with several species in Nepal. B.Careyanum spreads from this as far south as 
Martaban, and B. odoratissimum is common to it, with China. Dendrobium, however, 
which gives its name to the tribe, is the most numerous in species, though these are not 
in proportion widely distributed, as they are chiefly confined to the tropical parts of Asia, 
two being also found in China and Japan, four in tropical New Holland, and one in 
the Society Islands. Several species extend as far as Nepal, but only one has as yet 
been found further north in the Himalayas, and that is D. alpestre, figured in the 
' present work, which is very closely allied to, and may be only a variety of, 
D. denudans, discovered in Nepal. D. alpestre is found on the oaks and rhododen- 
dra of the Mussooree Range, especially on those of the part called the Abbey Hill. 
The tribe of Epidendree, so named from an American Epiphyte, chiefly inhabit the 
intra-tropical regions of the New World, but also of Asia; a few extend northwards 
into India and China, and one species, Bletia aphylla, remarkable for being destitute 
of leaves, extends into Florida and South Carolina. A few species of Epidendrum attain 
elevations of 8,000 and 9,000 feet on the Andes of New Granada: so, in the Himalayas, 
a species of Spathoglottis is mentioned from Gossainthan, but the elevation is not indi- 
cated. The Indian species are chiefly found in the southern parts, but extend along the 
Himalayas as far as Nepal. The genera Jpsea, Cytheris, and Ania, do not extend beyond 
Silhet, where Bletia obcordata is also found, and is remarkable as belonging to a genus, 
of which several species are found in tropical America, with one in Madagascar, and 
another in Mauritius ; B. hyacinthina, a native of China and Japan, is naturalized in 
the Calcutta Botanic Garden. Spathoglottis, Arundina, and Phajus, found in the Indian 
Archipelago, and also in China, extend likewise to Silhet and Nepal: the last includes 
among its species, many which are highly ornamental. Apaturia having one species in 
China, near Macao, extends from Ceylon to Silhet, and as far as 284° N. latitude ; 
A. Smithiana having been found by Dr.Wallich in the jungles near Kadjuree Ghaut in 
Oude. The species of Orchidea, figured by Dr. Wallich in his Plante Asiatice Rariores, 
belong to the tribes Malaxridee@ and Epidendree. 
The Vandee, named from the Sanscrit Vanda, a name wali to some sighs 31 
Orchidee, but more especially to Vanda Rovburghii, indicates that some at least of this 
tribe are found in India, as indeed is also apparent from most of the Orchidee figured 
in Roxburgh’s Coromandel Plants belonging to this tribe, though many of the most 
ornamental genera are S. American, as Mavzillaria, Cattleya, Catasetum, Stanhopea, 
Gongora, Coryanthes, Burlingtonia, Oncidium. Endlicher has briefly stated, that they 
are either epiphytes or terrestrial: the American species have in general pseudo-bulbs, © 
with but few leaves, while the Asiatic are chiefly caulescent. They are distributed in 
almost equal numbers, in intra-tropical Asia and America.. Calypso alone inhabits the 
extreme north, or between 60° and 68°, both of the Old and New World, and the 
same species, C. borealis, is indigenous in both. But some are found at considerable 
elevations
