This remarkable species differs from A. crassifolius (Benth.) 

 Berg in its larger leaves, these almost always deeply emarginate 

 at the base, and in having the lobes of the calyx long, acute, triangu- 

 lar, and caducous. Further, our species is a relatively large tree, 

 while the latter, compared in its habit with Calycolpiis glaher, is 

 barely more than a shrub. The wood is very hard and known under 

 the name " gasparillo."
