four or five roundish petals, which are flat, large and spreading ; the 
filaments are twenty to twenty-five in number, awl-shaped, and about 
the length of the calyx ; anthers erect, four-grooved ; the pistillum 
is an inferior germ ; style filiform, four or five-parted ; stigmas sim- 
ple ; the pericarpium is an ovate capsule, acuminate at both ends, 
naked at the top by the calyx being barked, four or five-celled ; par- 
titions contrary ; the seeds are numerous, oblong, small, decumbent, 
arilled, and fastened to the thickened edge of the partitions ; arils 
club-shaped, acuminate, toothed at the base. This shrub also sends 
up a great number of stalks, which are very slender, from the root, 
seven or eight feet in height, having a gray bark, and putting forth 
several short branches from their sides ; the leaves are either ovate 
or ovate-lanceolate ; those upon the young shoots are three inches 
and a half long, and two broad in the middle, terminating in acute 
points, and having several indentures on their eyes ; they are rough,
