Discussion
The early collections of A. leucophylla var. vaupesensis were misidentified as Pithecellobium microcalyx, from which they are clearly different in plane or shallowly convex, not mounded and small-pored leaf-nectaries, and by larger calyces, more coriaceous leaflets, and basally dilated filaments of the capitulum’s terminal flower.
