17. Viola palmata angellae (Pollard). (PI. XXXIV, fig. ii.) 



Viola angclUe Pollard, 1902, Torreya, II, No. 2, p. 24. 



Range. — Found so far only in the neighborhood of Cheyney, Chester 

 county, Pennsylvania. 



Habitat. — Rich woodland. 



This violet (No. 3,094, Herb., W. S.) I collected on June 22, 1902, it 

 being then well past the flowering stage. Comparison with typical spec- 

 imens from Grange, New Jersey, kindly sent me by Miss Lillic Angell, 

 seems to prove the identity of the two, and Prof. Greene coincides 

 with my identification. All the leaves, even the earliest (wliich are 

 still retained), are cut, the later ones having the incisions rather rounded 

 at the base, and the lobes, except the middle, are quite uniform. The 

 difference in the appearance of the leaves between this and the other 

 forms can be seen by comparing the figures on the plate. The petioles 

 and the veins on the under side of the leaf are quite pubescent, but the 

 upper surface is but slightly so. Leaves 70 x 75 mm. ; petioles 

 150-17.5 mm. long. Cleistogenes on deflexed or prostrate peduncles 

 20 mm. in length. 



18. Viola septemloba Le Conte. (PI. XXXV, fig. ii; PI. XXXIX, fig. iii.) 



\'iola septemloba Le Conte, 1S28, Ann. Lye. N. Y., II, p. 141. 



Range. — Apparently a southern species, ranging across the southern 

 border of Pennsylvania. I have it from Kennett Square and several 

 miles north of Coatesvillc, both in Chester county. 



Habitat. — Low moist woodland.

 Pennock. No. 5,112, Herb. W. S. Flowers very large, 25 mm. broad, 

 violet-]3urpje, distinctly darker blue near the base of the petals, white 

 basal area well developed ; upper petals particularly large, 10 x 20 mm. ; 

 lower petals glabrous and beard on laterals short and restricted; sepals 

 very broad and relatively short; scapes 125 mm. long, glabrous. 

 Leaves all deeply cut, except some of tlie earliest, in which the in- 

 dentations are slight; segments of the later leaves taper rapidly to 

 scarcely more than a millimeter in width at base ; 7 to 9 principal divi- 

 sions; earliest leaves 30x35, later 50x60 mm., glabrous, except for 

 a fringe of very minute hairs on the later leaves ; petioles respectively 

 50 and 120 mm., glaljrous; cleistogenes 30 mm. long. 



Fruiting specimens. Kennett Square, May 25, 1902. No. 5,113, 

 Herb. W. S. Leaves 90 x 100 mm., with some ver}^ minute hairs above

This beautiful and distinct violet I have long considered to be
