coupled with such conflicting statements as this. I am aware that 

 some forms of the fimhriatula gi'oup with nearly or entirely glabrous 

 foliage occur in the New Jersey coast districts, but have not as yet had 

 opportunities for studying them. 



24. Viola sagitatta Ait. (PI. XXXVI, figs, i-iii; PI. XXXVIII, fig. i.) 



Viola sagittata Aiton, 1789, Hort. Kewensis, III, p. 287. 



Range. — Southeastern Pennsylvania, central and northern New 

 Jersey, southward through the Delaware valley. 



Habitat. — Moist meadows (forms occur also in dry ground). 



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

 vania, April 25, 1903. No. 5,133, Herb., W. S. Flower 15-18 mm. 

 broad, dark purple ("violet" of Ridgway); all petals strongly veined 

 with a darker shade, bases white, sometimes running out on upper 

 petals to form a white spot at the point where they are reflexed ; 

 beard on laterals in a large basal patch, from which a scattered 

 pubescence extends on to the purple area; base of lower and 

 often exposed part of upper petals pubescent; upper petals usually 

 large, rounded and nearly flat, and sometimes emarginate. Sepals 

 linear-lanceolate, acute; scape glabrous, 50 mm. long. Leaves some- 

 what variable, the earliest nearly triangular, the others ovate-oblong 

 or sagittate, generally rounded at the apex, crenate, with two or three 

 prominent teeth at the base, glabrous, 8x12-12x25 mm.; petioles 

 15-45 mm., glabrous. 



Later specimens, Tinicum, May 9, 1903, nearl}' out of bloom. Foli- 

 age quite glabrous throughout, leaves 12 x 45, sagittate, acute ; petioles 

 90-110 mm.; scapes 100-140. 



Fruiting plants, Tinicum, May 23, 1903. No. 5,135, Herb., W. S. 

 Leaves strongly auriculate-toothed at base, 80x20 mm., 40 mm. 

 across base, petioles 150 mm. Cleistogcnes erect on peduncles 150 

 mm. tall. Specimens from near Haddonfield, New Jersey, June 27, 

 1903, No. 5,138, Herb., W. S., have leaves 100 mm. long and 60 mm. 

 across the base; petioles 220 mm. These plants are somewhat pu- 

 bescent, notably on the margins of the leaves, and present some forms 

 perplexingly like emarginata (PI. XXXAT, fig. iv). Others, to all 

 appearances sagittata in leaf, form, etc., from dry sandy hillisdes near 

 Newtown Square, Pennsylvania, are quite pubescent on both blades 

 and petioles as well as on the scapes. These require further study. . 



25. Viola emarginata Nutt. (PI. XXXVI, figs, iv-v; PI. XXXVIII, fig. ii.) 



Viola emarginata Nuttall, 1818, Genera, I, p. 147.
