Perennial from a slender creeping rootstock, 13°-3° 
tall, at first erect, later generally decumbent and 
spreading, viscid and glandular, and villous with 
long spreading jointed flat hairs; leaves large, blade 
generally over 2’ long, usually broadly cordate, often 
acute and very rarely with an elongated tip, thick, 
more or less sinuately toothed, or sometimes suben- 
tire; calyx long-villous, lobes triangular, generally 
shorter than the tube; corolla 8-10” in diameter, 
greenish yellow with a brownish or purplish center; 
anthers mostly yellow; berry yellow. 
In rich soil, especially where the surface has been 
disturbed, New Brunswick to Saskatchewan, Florida, 
Colorado and Texas. The most common of our species, 
and includes several races. 
Physalis peruviana L., a native of South America, is cultivated for its fruit and often escapes. 
It resembles P. heterophylla, but differs in the leaves, which have a long tip, and in the pubes- 
cence, which is shorter, denser, and not at all viscid. Cape gooseberry. Strawberry tomato. 
Peruvian ground-cherry. Husk tomato. 
15. Pnysalis comata Rydberg. Hillside 
Ground-Cherry. Fig. 3710. 
P. comata Rydberg, Bull. Torr. Club 22: 306. 1895. 
Perennial, erect, about 14° high; pubescence fine 
and short, that on the calyx, peduncles and upper 
branches mixed with long white flat jointed hairs. 
Like P. heterophylla Nees (P. virginiana Gray, not 
Mill.), but leaves smaller, blade not over 2’ long, 
round-ovate, scarcely at all cordate at the base, about 
2’ long, thin, somewhat repand-dentate, or nearly 
entire; petioles as long as the leaves; peduncles as 
long as the fruiting calyx, or longer; corolla green- 
ish yellow, with brown center, 6-10” in diameter; 
fruiting calyx of thin texture, round-ovoid, some- 
what Io-angled, scarcely sunken at the base. 
Hillsides of Nebraska, Kansas, Colorado and Texas. 
Rare.

P. rotundata Rydberg, Mem. Torr. Club 4: 352. 1896. 
Diffuse and spreading, zigzag, generally dichoto- 
mously much branched, from a perennial rootstock, 
densely and finely viscid-pubescent, usually more 
glandular than the preceding. Leaves nearly orbicu- 
lar with more or less cordate base, 1’-13’ in diam- 
eter, with small teeth; petioles short, more or less 
winged; peduncles short, in fruit scarcely more 
than half the length of the calyx; corolla 8” in 
diameter, greenish yellow with a brownish center; 
fruiting calyx ovoid, slightly angled, scarcely sunken 
at the base.
