is very great at certain seasons. They are found in Georgia 
Pernambuco, Ceara, Uringay, and French Guiana, but not so 
abundantly as in the Malayan islands, where the temperature 
attains from 75 to 80°, and is damp to excess. Brazil abounds 
with them, possessing, as it does, an atmosphere of heat and 
moisture. In Madagascar they are plentiful; here the tempera¬ 
ture reaches from 80 to 84°, with a corresponding amount of 
humidity. In Grenada and Peru they are also found, the ther¬ 
mometer indicating 60 to nearly 70°; but in equally high lati¬ 
tudes in Africa they do not exist, as the heat is very great, 
and dew but seldom falls,—the want of moisture being fatal to 
them. 
On the other hand, in Sierra Leone, where the vapours rise 
in great quantities, so much so as to be inimical to European 
constitutions, the Orchideae again abound,—as also in South 
America, in the gorges of the Andes, and in Guatemala, where 
the average temperature is 65°, with plenty of moisture. They 
are found, too, in Trinidad, Demerara, and Rio Janeiro. They 
are met with in the savannahs of Jamaica, usually growing 
on the ebony (Brya ebernus) and other lofty trees. In Bengal, 
Surinam, Venezuela, Algoa Bay, Ragabasa, Chittagong, and 
Penang, they are scarce; but in some parts of China they are 
valuable as well as numerous. Japan produces a few, between 
Osacco and Jedo ; there are some also in Havanna, Madeira, 
Totola, the Organ Mountains, and the Society Islands in the 
South Seas. They are found in the swampy parts of the woods 
of Malacca, growing upon the tamarind (Tamarindus indicus); 
also in the Cicar Mountains, the islands of Ternate, Martinico, 
and New Zealand, but not in such quantity as in Manilla, 
Ceylon, Singapoor, Xalopa,—and in the West Indian islands, 
growing on the calabash trees (Crescentia cucurbitina). There 
are also a few in Hispaniola, Delagoa Bay, and Monte Video ; 
also in St. Vincent, and New Caledonia. As all those places 
in which they flourish abound in heat and moisture, it is evi¬ 
dent that to these elements we must look for the means by which 
we may cultivate this singular class of plants. 
Light undoubtedly exercises great influence on plants, as on 
all creative matter, but over this we have little control, nor is it 
of so much consequence ;—as these plants differ so materially 
from most others in the formation of their roots, being of a fleshy
