SOLANACEAE 985 
corolla yellow with a dark center, about 2 cm. in diameter: anthers generally yellow, 
sometimes tinged with purple: fruiting calyx 3-4 cm. long, 2.5-3 em. in diameter, pyram- 
idal to ovoid-conie, indistinctly 10-angled, deeply sunken at the base: berry small, in 
the center of the calyx. 
In rich soil, Arkansas and Texas. 
16. Physalis lanceolata Michx. Perennial, sparingly hairy, the rootstock appar- 
ently, as a rule, slender and creeping. Stems about 5 dm. tall, at first erect, later spreading 
or diffuse, only slightly angled, sparingly hirsute with flat hairs: leaf-blades broadly ob- 
lanceolate or spatulate, tapering into the petiole, acute or obtuse, nearly always entire, 
rarely wavy, but not sinuately toothed, thickish, sparingly pubescent with short hairs: 
peduncles 1-2 em. long, in fruit reflexed : calyx strigose or vilious, rarely glabrous ; lobes 
triangular-lanceolate : corolla dullish yellow with a brownish center, about 1.5 cm. in 
diameter: fruiting calyx rounded ovoid, not sunken at the base, indistinctly 10-angled : 
berry yellow or greenish yellow. 
On dry plains, North Carolina to Wyoming, South Carolina and New Mexico, 
17. Physalis pumila Nutt. Perennial from slender rootstocks, 0.5-1 m. high, hirsute. 
Stems obscurely angled : leaf-blades thick, generally broadly ovate, acute at both ends and 
somewhat rhomboid, the lower often obtuse and obovate, generally much larger than in 
the preceding species, 5-10 cm. long, entire or seldom sinuate, on petioles 2-3 cm. long at 
maturity : calyx densely hirsute, not stellate; lobes triangular, generally a little shorter 
than the tube: corolla yellow with brown center, 1.5-2 cm. in* diameter: fruiting calyx 
generally more elongated than in the preceding, 4-5 cm. long, oblong-ovoid, a little 
sunken at the base, indistinctly 10-angled. 
On plains and prairies, Missouri to Colorado and Texas. 
18. Physalis Virginiana Mill. Perennial from a somewhat fleshy rootstock, pu- 
bescent. Stems 0.5-1 m. tall, dichotomously branched, somewhat angular, pubescent with 
appressed hairs, sometimes somewhat glandular, or in some forms nearly glabrous: leaf- 
blades ovate-lanceolate, tapering to both ends, 3-6 cm. long, generally more or less sinu- 
ately dentate, often yellowish green: peduncles 1-2 cm. long, generally erect, or becoming 
curved, but scarcely reflexed: calyx strigose-hirsute, or at least puberulent ; lobes tri- 
angular or broadly lanceolate, nearly equalling the tube in length’: corolla sulphur-yellow 
with purplish spots, 1.5-2.5 cm. in diameter: anthers yellow: fruiting calyx pyramidal- 
ovoid, 5-angled and sunken at the base: berry reddish. [P. lanceolata Chapm., not Michx. 
P. monticola Mohr. } 
In loose soil, New York to Manitoba and Colorado, south to Florida and Louisiana. 
19. Physalis rigida Pollard & Ball. Perennial from a thick rootstock, resembling 
in habit P. subglabrata. Stems strict, angled, more or less branching, 3-4 dm. tall, hispid- 
pubescent with flat hairs, especially above : leaf-blades firm, ovate-lanceolate, wavy-mar- 
gined, densely pubescent when young, tapering at both ends: calyx pubescent with flat 
hairs, especially on the veins and at the base: lobes triangular: corolla 1-1.5 em. wide, 
yellow with purple center : fruiting calyx ovoid, nearly glabrous, obscurely 10-angled, 2.5-3 
cm. long, somewhat retuse at the base. 
In waste grounds, Louisiana to Arkansas and Tennessee. 
20. Physalis intermédia Rydb. Perennial, puberulent, and sometimes a little viscid 
when young. Stems 3-8 dm. tall, dichotomously branched, angled and striate, the upper 
portion with longer hairs and somewhat viscid : leaf-blades ovate or ovate-lanceolate, acute, 
4-6 cm. long, often oblique at the base, slightly sinuately toothed or nearly entire, very 
thin, light green, puberulent or glabrate : peduncles 1-2 cm. long, recurved at maturity, 
hairy : calyx puberulent or hirsute with appressed hairs; lobes broadly lanceolate, about 
equalling the tube: corolla sulphur-yellow with purplish spots, 1-2 cm. in diameter: 
anthers yellow : fruiting calyx ovoid, slightly 5-angled and slightly sunken at the base. 
[P. Virginiana intermedia Rydb.] 
In dry soil, Pennsylvania to Indiana, south ward to Florida and Texas. 
21. Physalis arenícola Kearney. Perennial from slender horizontal rootstocks, 
sparingly hairy. Stems 2-4 dm. tall, diffuse, striate, light green, the pubescence mostly 
of simple hairs, but sometimes a little glandular, in age deciduous except on the nerves 
of the calyx : leaf-blades relatively small, 1.5-6 cm. long, but sometimes 8 cm., ovate-cor- 
date, truncate or cuneate at the base, irregularly angulate-dentate, pubescence, if any, 
=e the veins, which are generally prominent and conspicuously reticulated : peduncles 
slender: calyx-lobes triangular-lanceolate, equalling the tube in length : corolla 1.5-2 em. 
in diameter, light yellow : anthers yellow: fruiting calyx 3 cm. long, narrowly ovoid or 
rather oblong-pyramidal or nearly cylindric, conspicuously reticulated : berry light yellow.
