|discussion=<p>Species ca. 90 (24, including 1 hybrid, in the flora).</p><!--
--><p>Physalis is recognizable by the fruiting calyx that enlarges and inflates to completely enclose the berry, and pendent or nodding flowers borne singly at each node; most members also have an unlobed, yellow or cream-yellow, campanulate-rotate corolla. Physalis solanacea is atypical in having an urceolate corolla that is mostly or completely lurid purple; the molecular phylogenetic analysis by M. Whitson and P. S. Manos (2005) showed that it is part of a clade of more typical species. Their study also supported treatment of Calliphysalis and Alkekengi as genera distinct from Physalis.</p><!--
--><p>The variable morphology of Physalis species has resulted in many misidentified herbarium specimens. Hair morphology is important in identifying most taxa.</p><!--
--><p>Two species occur as waifs in the flora area: Physalis minima Linnaeus, native to the New World tropics, has been collected as a weed in sugarcane fields and sandy open pastures in Louisiana; and P. ixocarpa Brotero ex Hornemann [including var. parviflora (Waterfall) Kartesz & Gandhi and var. immaculata (Waterfall) Kartesz & Gandhi], native to Mexico, has been collected sporadically from disturbed sites in the United States and Canada.</p><!--
--><p>Several species of Physalis are commonly cultivated for their edible berries: P. philadelphica (tomatillo) has fruits with a flavor reminiscent of tomato and is used in Mexican-style salsa; P. minima (pygmy groundcherry) has fruits similar to a cherry tomato; and P. peruviana Linnaeus (cape gooseberry) and P. grisea (strawberry tomato) have sweet fruits that are used in pies, jams, sauces, and as a garnish. The berries of many wild-growing species are eaten as well. Fruits of P. minima and P. peruviana are also used worldwide as an antispasmodic, diuretic, antiseptic, sedative, and analgesic. Unripe fruits and foliage of Physalis species contain solanine and other solanidine alkaloids and are toxic if ingested in large quantities.</p><!--
--><p>After this manuscript was completed, Physalis macrosperma Pyne, E. L. Bridges & Orzell was published describing plants similar to P. heterophylla but with larger fruiting calyces and seeds. Further study is needed to clarify the disposition of this taxon.</p>
