POLYGALACE.®. 
Hight species and one variety of the genus Polygala have been re- 
corded in the State. Of these Polygala Senega .., Polygala Senega latifolia 
Torr. & Gray and Polygala viridescens L. (=P. sanguinia L.) are of general 
distribution and fairly abundant. 
The following are reported from a single station: 
P, ambigua Nutt. =(P. verticillata var. ambigua Wood), from Gibson 
and Posey counties, upon the authority of Dr. Schneck. 
P. cruciata l., from Cass County, by Dr. Robert Hessler. 
P. Nuttallii Torr. & Gray, from Jefferson County, by J. M. Coulter. 
P. verticillata L. is reported from only two stations, Jefferson County 
and Noble County, while P. polygama Walt. is also reported but from two 
counties, Vigo and Elkhart. The difficulty of discriminating the species 
of this genus, because of their great variability and because of the fact 
that nearly related forms tend to become confluent, makes the inclusion 
of these forms reported from a single station a matter of some doubt. 
The material examined verifying the references has been so scant that 
critical study has been impossible. There is, however, in no instance any 
range improbability in the record. The well-known accuracy of the botan- 
ists reporting these forms is sufficient to justify their inclusion in the list. 
It is especially desirable that those in charge of herbaria should examine 
their Polygalas in the hope of both extending the range of these forms 
and justifying their inclusion in the State list. 
VIOLACE®. 
Sixteen species of the genus Viola have been recorded from the State, 
at least four of which seem questionable, so much so, indeed, that without 
additional evidence they should be excluded from the State list. 
Viola hastata Michx., reported only from Clark County, upon the au- 
thority of Baird and Taylor, is a mountain form. It occurs in the Alle- 
ghanies in Pennsylvania and follows the system southward. It has an 
additional station in the extreme northeastern part of Ohio, but apart 
from this is confined to the mountain regions. It is closely allied to V. 
pubescens, Ait.,, from which it differs essentially in the size of the stipules. 
The halberd-shaped leaf often passing into an oblong to heart-shaped, 
while the broadly heart-shaped leaves of pubescens as frequently narrow.
