Hab. Bio Uapes, tributary of tbe Amazon, Brazil, in a 
forest near Jauarate-Cochoeira, Ii. Spruce, n. 2540. 
This noble species is, perhaps, the tallest of the genus, the 
largest specimens that came under Mr. Spruce’s notice, he 
observes, were 4| feet high : so that I have thought the name 
of subarborescens not inappropriate. The leaves on the stipes 
are close pressed, dark green, ovate, very distant, upwards 
they gradually, as it were, pass into the foliage of the ffondose 
portion. The stipules are remarkably small in proportion to 
the size of the leaves.
