becomes matured on some of the branches of the panicle. 
The drupe is black, the dry sarcocarp adhering firmly to the 
thin coriaceous putamen, which is 8 lines long, 6 lines broad, 
compressed on two opposite faces, each of which is marked by a 
very shallow groove extending from the base beyond the centre ; 
corresponding with these grooves is an internal septiform con- 
dyle, which divides the cell for two- thirds of its length into two 
marsupial pouches : the seed which fills the cell is thus deeply 
hippocrepiform. 
Dr. Eichler has associated with this nearly all the species of 
Hijperbcena here described, amalgamating them under the name 
of Pachygone Domingensis, thus falling into the double mistake 
of confounding together different genera and different species.

This plant differs from the preceding species in its nearly 
orbicular leaves truncated at base, undulating on their thickened 
margin, with an extremely small apicular point, a comparatively 
much longer petiole, and a smaller, rounder, and more testaceous 
putamen. The leaves are 2^-21 inches long, 2-2^ inches broad, 
on a petiole inch long. The fructiferous racemes, solitary 
or geminate above each axil, are 2-2J inches long, having from 
four to six drupiferous pedicels 3-4 lines long •, the putauien is 
5 lines long, 4^ lines broad one way, 4 lines wide the other; 
the condylar semidissepiment, corresponding with the external 
furrows on each face, extends 4 lines within the cell, leaving a bi- 
marsupial space filled by the hippocrepiform exalbuminous seed.
