Description Unarmed herbs or rarely shrubs, pubescent with simple, often glandular or viscid, rarely dendritic hairs, sometimes sarmentose. Leaves simple and entire, shallowly toothed or lobed; petiolate; minor leaves when present resembling the major leaves. Inflorescence axillary, bracts obsolete, pedicels solitary or rarely in small fascicles, often elongating and cernuus in fruit. Flowers perfect and mostly nodding, calyx valvate, 5-lobed, accrescent and loosely enveloping the fruit or nearly so, remaining flexible or becoming woody-chartaceous; corollas yellow (Panama), often marked in the throat, funnelform -or rotate, sometimes reflexed, induplicate-valvate, the margin nearly entire or with 5 short, ovate-deltoid to subulate lobes; stamens mostly equal, the filaments inserted in the corolla tube, pubescent or not, the anthers all fertile, yellow or with various amounts of blue or purple and drying greenish, oblong-ovoid, basifixed, opening by longitudinal slits, in some species twisting and curling, the connective not apparent; ovary 2-locular, the many ovules anatropous, the style exserted, the stigma small. Fruit a juicy or fleshy, slightly stalked, many-seeded berry, glabrous but some- times viscid; seeds compressed, slightly rugose, the embryo circinnate at the periphery of the seed.
Habit herbs or rarely shrubs
Distribution Physalis has its greatest number of species in Mexico, but some species are found in Central and South America and a few occur in the Old World.
Note About 90 species are known. Most of the species now found in the Old World and probably those in Panama are widespread weeds. These plants are most common in ruderal sites. The berries are used for food, some species being cooked and others eaten out of hand. Physalis peruviana is a crop plant in South Africa, and P. alkekengi, a European species, is cultivated for ornament in temperate countries. Duke reported in the Darien Ethnobotanical Dictionary that "the fruits are eaten raw or cooked, especially as an additive to stews. They are some- times made into preserves by cooking in palm syrup." The name of the genus comes from a Greek word meaning bladder or bubble.
