British Honpuras : on open damp ground, near Sibune River, 4 May, 
1906, Prof. Morton E. Peck, no. 417 (type, in Gray Herb.). This 
species differs from A. angustifolia Benth. in its conspicuously ciliated 
stem and leaves, broader-based bracts, and smaller flowers; from 
A. salicariaefolia H. & B. it may be readily distinguished by its 
smaller flowers and much more sparing pubescence of much longer 
non-glandular hairs.
