364 ILLUSTRATIONS OF THE BOTANY OF [ Orchidew. 
common to these different parts of the world, the same species appear to be found in 
widely separated places. Thus, MWicrostylis Rheedii occurs in India, Java, and Otaheite. 
Liparis elata in India and Brazil? L. longipes in the mountains of Ceylon, as well as in 
those of the East of Bengal, (Lind]. Orchid. p. 21-30). Z. olivacea extends from Nepal 
to Mussooree, near the Abbey; where L. livida,a new species, was likewise discovered. 
The remaining Pleurothallide@ are either such as are peculiar to India and the 
Himalayas, or are found rather in the tropical parts, both of the Old and New World. 
Thus, Oberonia, which extends from Java, Ceylon, and Silhet, all along the Himalayas, 
has O. brevifolia common to the Mauritius, and the Society Islands. O. myosurus in 
the latter and Nepal. O. iridifolia, found in Otaheite by Sir J. Banks, occurs also in 
Ceylon, and extends from Taong Dong all along the vallies of the Himalaya, from 
Silhet to Nepal and the Deyra Doon. Dienia has two species in Mexico, one in Siberia, 
and three in Nepal. D. congesta is common to the last and China. D. cylindrostachya 
is the most common species in the Himalayas, extending from Nepal to Mussooree and 
Simla. Otochilus is a Himalayan epiphytal genus from Silhet and Nepal. Pholidota 
occurs in these, as well as in Java and Ceylon; the species P. imbricata in Nepal, 
Silhet, Martaban, and Tavoy. Empusaria is a Himalayan genus, of which the species, 
E. paradoxa, extends with Microstylis Wallichiana from Nepal to Musscoree, and both 
are allied to Northern Malavidee. Celogyne is one of the most widely diffused, as 
it is one of the most ornamental, of the Himalayan Malavidee. ‘Species are found in 
Java, Tavoy, and Ceylon, as well as in China and Japan. They extend all along 
the Himalayas to Mussooree and Lundour.  C. cristata and ocellata, found in Silhet, 
extend as far north as the valleys of Sirmore and Kemaon. The delicately beautiful 
C. precox extends to as high a latitude, but to a greater elevation, being found orna- 
menting, with its large richly-coloured flowers, the branches of oaks on Lundour 
at 7,500 feet of elevation, in 30° of N. latitude; but only during the moisture of the 
rainy season. C. fimbriata is a species which is found in China, as well as, (or a very 
nearly allied species), in Nepal and Kemaon. 
_ The tribe of Dendrobrie are chiefly found in tropical parts of the world; but, as in 
others, a few extend beyond these limits, as well as to considerable elevations. Most — 
of the genera included in the Indian Flora are Asiatic, and chiefly found in southern 
latitudes, as Trias, Phreatia, Evia, Aporum, and Mycaridanthes. Of the last, one 
species occurs in Nepal, where Monomeria is also found. Phreatia and Eria occur 
both in Java and Ceylon; the latter also in China, and along the Himalayas from 
Pundua, as far as the valleys of the Choor, where are found E. alba and E. flava, first | 
discovered in Nepal. Polystachya contains only five species, but these are widely 
diffused ; one species alone, P. luteola, having the distribution of the genus, with 
the exception of not being found in Sierra Leone, but occurring in Mexico, the 
West Indies, Mauritius, as well as in Ceylon. Cirrhopetalum and Bolbophyllum are simi- 
larly and widely distributed ; and the first has one species, C. Thouarsii, in Otaheite, 
_ Madagascar, Mauritius, and J ava. C. Rorburghii is found at the mouths of the . 
Ganges,
