MASDEVALLIA SIMULA. 
There appears to be some doubt as to whether all the different varieties belong to 
the same species. Up to this moment I have not been able to detect any structural 
difference,—merely a larger or smaller development in any plant from the different 
localities. The form represented in the accompanying plate is a good medium develop- 
ment of the species, as it is found in the vicinity of Aguadas and Sonson, and other 
parts of Antioquia. The smallest form is met with near Popavan and on the Alto del 
Mojanda, near Quito, the leaves seldom exceeding 3 centimétres (about 14 inch) in 
length. The largest form, the leaves of which attain a length of 16 or 18 centimétres 
(63 or 7 inches), grows on rocks and trees in the damp and shady woods on the western 
slopes of the Corazén mountains, near Quito, at an elevation of 2,000 to 2,400 métres 
(6,500 to 7,800 feet).
