less strigose-hairy with flat hairs, sometimes somewhat glandular, 
or in some forms nearly glabrous; leaves ovate-lanceolate, taper- 
dentate, often yellowish green; peduncles 1-2 cm. long, generally 
erect, in fruit curved, but scarcely reflexed ; calyx strigose, hirsute, 
or atleast puberulent, lobes triangular or broadly lanceolate, nearly 
equalling the tube; corolla sulphur-yellow with purplish spots, 
115—214 cm. in diameter ; anthers yellow ; fruiting calyx pyramidal- 
ovoid, 5-angled and sunken at the base ; berry reddish 
P. Virginiana is, next to P. heterophylla, the most common of 
our species. It grows in rich soil and frequents open places, such 
as fields, roadsides, borders of woods. Specimens from about 
IOO localities have been examined, which show that it is common 
from Michigan and Minnesota to Colorado and Louisiana. Be- 
sides I have seen specimens from the following states : 
New York: Dr. N. L. Britton. 
South Carolina: Wm. Canby. 
Florida : Chapman. 
Georgia: Le Conte. 
Manitoba: E. Bourgeau, 1859. 
Like P. heterophylla, it is very variable. The original form de- 
scribed and figured by Miller is more densely hairy, with longer 
hairs, sometimes even somewhat glutinous, and with broad and 
more deeply sinuate-toothed leaves. It is comparatively rare 
and probably had not been seen by Gray, when he applied the 
name P. Virginiana to P. heterophylla Nees. The following speci- 
mens of this form are in our herbaria: 
Illinois: Vasey. 
Michigan: - C. F. Wheeler, 1890. 
Minnesota : Dr. Jarvis ; J. H. Sandberg, no. 975, 1891. 
Towa: Hitchcock, 1889; J. A. Rolfs, 1891 
Tennessee: Gattinger, 1886; Scribner, 1890. 
Missowi: LH Pammel. 
Kansas: J. E. Bodin. 
Wisconsin: S. N. Watson. 
The common, less hairy form has more indistinctly toothed 
leaves. The usual color of the plant is more or less yellowish 
green. The Florida specimens are more slender and have thinner 
leaves, and are in some cases hard to distinguish from forms of
