Masprvariia Epuipprum, 
the State of Cauca, as far south as the volcan 
of Popayan it attains the largest proportio 
the flowers. Masses measuring 40 or 50 centimetres (16 or 20 inches) across are 
frequently met with. About three years ago (1886) I also found the variety acrochordonia 
on the eastern declivities of the Eastern Andes of Cuenca, in Ecuador. The plants 
from that locality are much smaller, and the flowers only about half the size of those of 
M. Ephippium in Colombia. 
0 of Sotara, near Popayan. In the vicinity 
us, both in masses of root and in the size of 
M. Ephippium is never found growing in great abundance over a large area. It 
invariably occupies small localities—perhaps a small portion of a mountain slope—and 
will not be met with again for a great distance. 
The annual mean temperature ranges between 15° and 18° Centigrade (59° and 
64°:4 Fahrenheit), according to the region.
