Description. — Flowering plant. Tinicuni, Delaware county, Pennsyl- 

 vania, May 3, 1902. No. 2,601, Herb. W. S. Flowers large, 25 mm, 

 broad, deep violet-purple, conspicuously bluer toward the base of the 

 petals, which is white; pubescence restricted to white area on lateral 

 petals; lower petal glabrous ; sepals ovate-lanceolate, broad, and rather 

 blunt; scapes slightly pubescent, 120 mm. long. Leaves moderately 

 pubescent above and below ; earliest 20 x 25 mm. , later ones 45 x 50 

 mm.; much lobed, but none of the incisions reaching more than 

 half-way to the base; petioles pubescent, 90-120 mm.; cleistogenes 

 on short horizontal peduncles 30 mm. long. 



Later plants, June 28, similar, but leaves nearly glabrous, except on 

 the veins beneath, size SO x 110 mm.; petioles 180, cleistogenes short, 

 dcflexed. Late summer leaves reach the dimensions of 120 x 150 

 mm., with petioles 300 mm. in length. 



The apparent rarity of this violet would make me hesitate in regard- 

 ing it as a separate form were it not for its very distinct characters 

 and the assurance of Prof. Greene. Probably I have not yet discovered 

 its stronghold, or perhaps it is rare in the vicinity of Philadelphia, l^ut 

 plentiful elsewhere.
