Hab. flio ITapes, tributary of the Amazon, Brazil, in a 

 forest near Jauarate-Cochoeira, R. 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 4J feet high : so that I have thought the name 

 of subarborescens not inappropriate. The leaves on the stipes 

 are close pressed, dark grejn, ovate, very distant, upwards 

 they gradually, as it were, pass into the foliage of the frondose 

 portion. The stipules are remarkably small in proportion to 

 the size of the leaves.
