are entirely absent. Most of the tropical forms are 
epiphytes, that is, they grow upon trees and usually have 
bulb-like or thickened stems and fleshy leaves for the 
conservation of their water supply, as, from their habitat, 
this supply must be precarious. In temperate regions 
nearly all of the species are terrestrial, and have thin leaves, 
the soil about their roots serving to protect them from the 
cold and also giving them a more constant water supply; 
they do not, therefore, need pseudobulbs or thickened 
stems. Coming from all parts of the world as they do, 
their blooming time varies greatly, so that at almost any 
time of the year, be it winter or summer, some of these 
interesting plants may be found in bloom. 
This house is the gift of Messrs. Daniel and Murry 
Guggenheim. Jt has a length of 140 feet and a breadth 
of 29 feet. It is divided into two compartments, 4 and B. 
In compartment J are the orchids requiring cool condi- 
tions. Here will be found: Coelogyne cristata and Paphioped- 
tlum insigne, of the Himalayan region, the latter species with 
many color variations, and one of the exceptions in a 
genus usually requiring the conditions of a stove house; 
some species of the genus Epidendrum; Lycaste, an Ameri- 
can genus; Odontoglossum, also of America; Oncidium, 
a large genus of tropical America, with a maximum de- 
velopment in South America; Masdevallia. 3 in large part, a 
genus of great altitudes in the American tropics; Pleurothal- 
lis, with much the same distribution as the preceding genus, 
many of the species being very small, some only a half 
inch tall; and Pletone, of the Old World. 
n compartment B are those requiring intermediate 
conditions as to temperature. Here, among others, will 
be found the genera: Cattleya, in most part, native of 
America only; Epidendrum, in part, also a large American 
group; Laelia, of American distribution; and Oncidium, 
in part, likewise American. 
House No. 6. This house is the same length as house 2, 
but is only about 21 feet wide, and is a little lower. It is 
also divided into two compartments, 4 and B.
