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 Portuguese man o' war (Physalia physalis), also known as the man-of-war [6] or bluebottle, [7] is a marine hydrozoan found in the Atlantic Ocean and the Indian Ocean. It is considered to be the same species as the Pacific man o' war or bluebottle , which is found mainly in the Pacific Ocean . [ 8 ]
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).

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 ...
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 ixocarpa – MHNT. The tomatillo (Physalis philadelphica and Physalis ixocarpa), also known as the Mexican husk tomato, is a plant of the nightshade family bearing small, spherical, and green or green-purple fruit of the same name. [1] Tomatillos originated in Mexico and were cultivated in the pre-Columbian era. [2]
The plant has a low, spreading habit, and fruits develop in a papery husk, as is characteristic of the genus. While most parts of the plant are toxic to humans due to the presence of solanine and solanidine, [2] the fruit becomes edible (and sweet) once it has ripened to yellow. (The papery husk, a calyx, remains toxic and should not be eaten.)
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.
