This is the common form of P. virginiana. Tt differs from the type slightly in the 
leaves, which are less sinuately toothed. ‘The original P, virginiana, described and 
figured by Miller, has deeply toothed leaves and the whole plant is more or less 
glutinous. It is a very rare form. 
The few poor specimens in this collection are more or less pubescent, with sinuately 
toothed or wavy-margined leaves, yellow fruit, and a pyramidal, angled, fruiting 
calyx with a sunken base, a character which distinguishes all forms of this species 
from 2’, lanceolata Mx. Lead City, altitude 1,600 m., July 6 (No. 909).
