it is supposed to be native. In New Jersey, south to Trenton 

 (Britton).

Description. — Flowering plants, Bartram's Garden, Philadelphia, 

 May 13, 1901. No. 1,083, Herb., W. S. Stem glabrous, several from 

 one root, 150 mm. high; stipules large laciniate, leaves cordate-ovate, 

 crenate, 30x35 mm., glabrous; petioles 20 mm. long, numerous 

 smaller glabrous radical leaves. Flowers creamy-white, 15-20 mm. 

 broad, lower and lateral petals lined with purplish-black, the formei- 

 well bearded near the base ; stipules linear-lanceolate ; pedicels 50-60 

 mm. long. 



Fruiting plants are 300 mm. high, with leaves 40x40 mm., quite 

 acutely pointed. Some plants produce cleistogamic flowers in the 

 upper axils.

Range. — From the highest Alleghanies to Philadelphia; in New 

 Jersey, northern counties south to Freehold, and casually in the lower 

 Delaware valley to Salem (Britton). 



Habitat. — Damp woodland, or sometimes open ground. 



Description. — Flowering plant, Crum creek, Delaware county, Penn- 

 sylvania, April 10, 1903. No. 5,165, Herb., W. S. Stems glabrous, 

 somewhat reclining, 70 mm. long, a number from the same root and 

 with numerous radical leaves ; stipules with lacunate margins. Leaves 

 reniform or nearly orbicular, crenate, 15 x 15 mm., lower cauline 18 

 mm. in length. Flowers pale lilac-purple, lower petals lined with black, 

 laterals slightly bearded; sepals linear-lanceolate. The lowest flower 

 is very long-pediceled (50 mm.) and overtops the rest of the plant; 

 there is usually one other true flower and often cleistogenes in the upper 

 axils. 



Fruiting plant, Crum creek, May 17, 1903. No. 5,166, Herb., W. S. 

 Stems 200 mm. high, leaves 30 x 30 mm. Usually two or three fruiting 

 pedicels and a cleistogene on each stem, each shorter than the one 

 below; radical leaves still persistent. 



While this is evidently closely allied to V. labradorica Schrank., the 

 fact that Prof. Greene has shown that there are several distinct forms 

 of this species in the northeastern part of the country makes it 

 desirable to retain the present name for our plant. It is almost cer- 

 tainly distinct from the Labrador form, but probably may be regarded 

 as a subspecies of it.
