Quite as abundant is the Meadow or Hooded Blue Violet (Viola 

 papilionacea Pursh) with nearly glabrous foliage, very large leaf 

 blades which are reniform or ovate, deep-blue flowers, the odd petal often 

 narrow and boat-shaped, usually beardless; capsules ellipsoid, green or 

 dark purple. Common in moist fields and groves, frequently about 

 dwellings. 



The Broad-leaved Wood Violet (Viola latiuscula Greene) 

 possesses broadly ovate-deltoid leaf blades, the earliest ones blunt and 

 tinged with purple beneath; petioles glandular-roughened; flowers violet- 

 purple. In dry, open woods in sand or gravel. 



The Southern Wood Violet (Viola hirsutula Brainerd) enters 

 our range only in southern New York. It is a small species with leaves 

 lying close to the ground, the blades orbicular to reniform, purplish 

 beneath, silvery pubescent above ; flowers reddish purple. 



The Northern Wood Violet (Viola septentrionalis Greene) 

 is common in moist, open woodlands south to Connecticut and Pennsyl- 

 vania. The foliage, except the earliest leaves, is hirsutulous. The leaf 

 blades are ovate to reniform, heart-shaped, ciliate and blunt; sepals blunt, 

 closely ciliolate nearly to the tip; flowers deep violet to pale lilac. 



LeConte's Violet 



Viola affinis LeConte 



Plate lasb 



Foliage nearly or quite smooth; rootstocks slender, branching, or the 

 plants growing in matted clusters. Early leaves narrowly ovate and heart- 

 shaped, more or less long pointed toward the apex, the margins crenate- 

 serrate; petioles slender and smooth. Flowers violet with a conspicuous 

 white center; the cleistogamous flowers small, on ascending stalks. 



Common in moist meadows, low woodlands and shady borders of 

 streams, New England to Wisconsin, south to Georgia and Alabama. 

 Flowering from April until June. The mature leaves of midsummer are 

 about 2 inches wide. 



The Northern Bog Violet (Viola nephrophylla Greene) 

 resembles LeConte's Violet in some respects, but the leaves are broader 

 and more blunt. It occurs in cold, mossy bogs and sometimes along 

 borders of streams and lakes from Quebec to British Columbia south to 

 Connecticut and Wisconsin. It appears to be abundant in a bog in Bergen 

 swamp, Genesee county.
