ry much like the former species, virens, that I was for 
some time inclined to consider them only varieties of one 
species, but attentive examinations made at various 
times, give me reason to think they are sufficiently dis- 
tinct. In the former, virens, the leaves continue green 
when dry, and are destitute of the two small, hollow 
glands on the base of the lower pair of veins, one on each 
of the lower ends of the rib, or nerve, which particular- 
ly mark flavescens. The panicles except those that ter- 
minate the twigs, are in this perfectly axillary ; in that far 
above the axills, and their insertions accompanied by two 
or three, vertically situated knobs or buds, as in some 
species of Capparis, &c. There the germ has never more 
than four ovula, inserted by pairs on opposite sides near 
the bottom of the cell; here are from eight to twelve 
ovula in the germ, inserted on opposite sides of the cell, 
from the base to near the top. There the stigma is large 
and more or less two-lobed; here’simple, In other res- 
pects they agree so well, that it seems unnecessary to 
figure more of flavescens, than the back of the base of one 
leaf, to shew the two glands.
