Physalins are steroidal constituents of Physalis plants which possess an unusual 13,14-seco-16,24-cyclo-steroidal ring skeleton (where the bond that is normally present between the 13 and 14 positions in other steroids is broken while a new bond between positions 16 and 24 is formed; see figure below).

A defining feature of Physalis is a large, papery husk derived from the calyx, which partly or fully encloses the fruit. [5] Many species bear edible fruit, and some species are cultivated. The typical Physalis fruit is similar to a firm tomato in texture, and like a sweet, tangy grape in flavor. [6]

The family Physaliidae is monotypic, consisting of only one genus, Physalia. [2] The genus is also monotypic, containing only P. physalis. [1] [3] There is a long history of the genus being described with multiple species, such as the Pacific man o' war (P. utriculus), however most of these species are now considered synonyms for P. physalis.
Physalis infinemundi is an extinct species of the genus Physalis (which includes Cape gooseberry, tomatillo, and ground cherries) known from two fossilised fruit found in the Laguna del Hunco Formation of Chubut Province, Argentina dating to the Eocene, around 52 million years old. The species name derives from "in fine mundi" means "at the end ...
Physalis angulata is an erect herbaceous annual plant belonging to the nightshade family Solanaceae. Its leaves are dark green and roughly oval, often with tooth shapes around the edge. Its leaves are dark green and roughly oval, often with tooth shapes around the edge.
However, along with other members of the genus Physalis it is an aggressive species in some parts of the United States. A specific example of the aggressive capabilities of P. virginiana is its effect on soybean production in Kentucky. The berries are often crushed during the soybean harvest which allows the Physalis seeds to cling to the ...
