Specimens examined : Guatemala. Hedges about Es- 

 cuintla (Smith, 2085 — the type in the U. S. National 

 Herbarium; Trelease, 15, 1915). Mixco {Trelease, 16, 

 1915). Fiscal {Beam, 6240, June, 1909). Also seen in 

 cultivation in the Plaza de Armas, Guatemala City, at 

 Guarda Viejo, and on the Pacific slope as far down as 

 Palo Gordo near Mazatenango. 



Apparently of the alliance of A. tequilana and A.

 The group is not unknown in the Pacific region to the 

 South.
