advisable to separate the Mexican Leelias from the Peruvian Odontoglossa. Nay, 1 apprehend that what I call the 
“ Peruvian house ” will itself have to be subdivided into two portions, one of which, 2. e. the warm portion, will contain 
such plants as the Trichopilias, the Anguloas, and such Odontoglossa as are met with below 6500 feet, while the other or 
cooler portion will be suited to an innumerable multitude of glorious Orchids that are met with at a still higher 
elevation. Already cultivators have discovered that O. Phalenopsis and O. nevium cannot be made to thrive in the 
same house, for though both are “cool” plants the former—coming as it does from a lower level—requires a decidedly 
warmer climate than the latter, and so it will be in many other cases which are not yet so distinctly understood.
