260 BRAINERD: FOUR HYBRIDS OF VIOLA PEDATIFIDA 
and the status of the plant is strikingly analogous to that of 
numbers 1 and 3 above described. The supposed hybrid has 
been recently again collected, by Mr. Paul C. Standley.* The 
leaves in his specimens are cut about halfway to the midrib; but 
on the same sheet are two detached leaves parted as in V. pedati- 
jida, indicating that this species grew with the anomalous plant.
