11. Viola cucullata leptosepala (Greene). 



Viola leptosepala Greene, 1902, Pittonia, V, p. 98. 



Range. — Shady bogs, western New Jersey; probably more extendecL 

 Description. — Flowering plants, Springvale, Camden county. New 

 Jersey, May 10, 190.3. No. 5,1.32, Herb. W. S. Generally similar to 

 cucullata, but much more slender and delicate and plants solitary; 

 leaves more elongate; flowers large, with remarkably long, slender 

 sepals, 12 mm. long and less than 2 in width. Scapes and petioles 

 very slender and with scattered hairs, most plentiful on the lower part. 



12. Viola crenulata Greene. (PI. XXXII, fig. iii.) 



Viola crenulata Greene, 1901, Pittonia, IV, p. 295. 



Range. — Only detected in Tinicum, Delaware county, Pennsylvania, 

 as yet. 



Habitat. — Open wet meadows and swamps, but in drier spots than 

 V. cucullata. 



Description. — Flowering plant. Tiniciun, Delaware county, Penn- 

 sylvania, April 25, 1903. No. 5,127, Herb., W. S. Flowers pale hlac- 

 blue, darker near the base of the petals, throat white, 12 mm. in diam- 

 eter; petals slender, the lower rather broad, slightly pubescent at base ; 

 laterals with conspicuous bearded patch; sepals slender lanceolate; 

 scapes 80 mm., glabrous. Leaves triangular-cordate, much attenuated 

 at apex, pale green, glabrous, except for very minute appresscd scat- 

 tered hairs on the veins above, size 20 x 2S, coarsely crenate (earliest 

 leaves less pointed); petioles 50 mm.; cleistogenes already 25 mm. 

 high. 



Late summer plants (August 15, 1903), past the fruiting stage, have 

 leaves 35 x 40, but otherwise exactly like the earlier ones; petioles 

 90 mm. long, which evidently represents the maximum growth of this 

 little plant. 



This delicate little violet, while related to the cucullata group, is 

 very distinct, differing in the color of both flowers and leaves, in the 

 shape of the latter and the very small size, being smaller in late summer 

 than V. cucullata when it is in early flower. The April specimens above 

 described had evidently been in flower some time, as evidenced by 

 the development of the cleistogenes.
