Violets are difficult to sort out, and this species is similar to the Canada Violet (V. canadensis), also fairly common in our area. Note, however, the rounded leaves with rounded teeth, the long spur of the flower, and the almost complete lack of yellow at the bases of the petals; these things persuade us that this is V. striata. Corrections, however, are always received with gratitude. These plants were blooming abundantly along the Trillium Trail in Fox Chapel.
