the corolla are broader, shorter, composed of small linear cells, 
which are contracted in the middle into a distinct nerve. Stylo-

purple anthers and stigmas in the white flowers, give this species 
a very pretty appearance.

The description is taken from the Virginia plant; the forms 
from Illinois and Texas constitute two distinct varieties.

This species bears some pesnihiaah to C. Polyzonorum on 
: one side, and to the three foregoing species on the other; to 
xu y the acuminate lobes of the corolla, to the first by. the 
Seemed ovary and pale greenish-yellow capsule ;* but it is dis- 
tinguished from both by the orbicular lobes of the generally large 
and more or less pentagonal calyx. . The inflorescence represents 
little umbels in 7, or approaches the glomerules of C’.. Polygeno- 
rum in 8. andy. ‘The lobes of the corolla are acute, resembling 
in shape those of the following species, in the Texan variety; or 
longer and finely acuminate, (similar to. C. verrucosa and C. his- 
pidula,) in the more northern forms. Stamens short, only half 
the length of the limb; anthers nearly globose. Seales large, 
ovate, fimbriate, sometimes exceeding the tube. Ovary and aps
