Fig. 3709

Physalis viscosa Pursh, Fl. Am. Sept. 157. 1814. Not L. 1753. Physalis heterophylla Nees, Linnaea 6: 463. 1831. Physalis virginiana A. Gray, Syn. Fl. 2: Part 1, 235.

1878. Not Mill. 1768.

Perennial from a slender creeping rootstock, 1 1/2°-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 pubescence, which is shorter, denser, and not at all viscid. Cape-gooseberry. Strawberry-tomato. Peruvian ground-cherry. Husk-tomato.

P. comata Rydberg, Bull. Torr. Club 22: 306. 1895.

Perennial, erect, about 1 1/2° 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 greenish yellow, with brown center, 6"-10" in diameter; fruiting calyx of thin texture, round-ovoid, somewhat 10-angled, scarcely sunken at the base.

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 orbicular with more or less cordate base, i'-1 2/3' in diameter, 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.
