At all localities where the *fringed polygala" was found, the 
plants were producing cleistogamous flowers near the roots. 
These flowers fertilized themselves much more readily than the 
showy ones at the summit of the stem and produced by far the 
greater amount of fruit.

Not one of our numerous specimens of the above species can 
be referred to the typical form, but all of them must be placed 
under the variety /atifola. The study of the specimens collected 
leads us to believe that the variety may be more prevalent than it 
is supposed to be, for this reason ; the best and constant charac- 
ter of the variety is the erose-denticulate margins of the leaves 
under a lens, which are easily overlooked, as they are not very 
conspicuous. The varietal name is a poor guide, and is in fact 
often misleading.
