in Colombia, between altitudes of 1,000 and 1,700 meters, but
nowhere common.

This was one of the earliest of the arboreal passionflowers to be
described. In the Flora Brasiliensis Masters referred to it specimens
from Venezuela, Colombia, Ecuador, and Peru. The Venezuelan
material was later segregated as a separate species P. Lindeniana;
the Ecuadorean specimen and the Peruvian one, which probably
came from Ecuador in reality, represent P. macrophylla.
The specimens which I have cited as P. arborea show considerable
variation in the size and shape of the leaves and in the width of the
sepals and petals, and I am inclined to believe that more than a
single species is represented, especially in view of the widely separated
localities at which this material was collected. However, as the
whole section Euastrophea is still in a state of much confusion and can
be satisfactorily dealt with only by assembling all available material
at one place for careful comparison, I prefer not to divide P. arborea
