and soaking. Herbal preparations are known to be administered internally and externally. Physalis plants grow in most soil types and do very well in poor soils and in pots. They require moisture until fruiting. Plants are susceptible to many of the common tomato diseases and pests, and other pests such as aphids, whiteflies, spider mites, and the false potato beetle (Leptinotarsa juncta) also attack them. Propagation is by seed. In the United States, Louisiana erroneously classifies Physalis subglabrata (smooth groundcherry) as a hallucinogenic plant, and its cultivation for other than ornamental purposes is outlawed under State Act 159 of 2005. In the Gran Chaco region of South America, the consumption of the different species of Physalis for food has declined due to sociocultural and environmental changes. Factors generally stem from the ongoing effects of colonization, including loss of ancestral territories to forestry exploitation and industrial agriculture as well as the decline of seasonal human migrations which were formerly part of the cycle of propagation, harvest, and consumption of Physalis. Subgenera and sections Physalis is divided into subgenera and sections. The taxonomy of Physalis is still an active area of taxonomic classification. About 75 to 90 species are placed in the genus. In 1831, Nees von Esenbeck was among the first researchers to complete a review of the Physalis species that had been described until that time in order to identify synonyms and subtaxa within the genus. In 1837, George Don named the sections proposed by Nees von Esenbeck, including three names that are still in use: Physalodendron for woody species, Eurostorhiza for perennials with rhizomatous roots, and Epeteiorhiza for annual species. Michel Félix Dunal in 1852 and Per Axel Rydberg in 1896 also published efforts to subdivide Physalis, although these were not generally consistent with the taxonomy advocated by Esenbeck and Don. Rydberg's taxonomy identified seven species groups within a section Rydberg called Euphysalis; these groups became the basis of sections which remain in use. Margaret Y. Menzel's research in the 20th century provided new insights into Physalis taxonomy, including the results of her crossing experiments with 28 Physalis species and their karyological data. The groups of species previously set up by Rydberg were raised to sections by this research. A summary of all taxonomic research regarding the genus was published in 1989 by Radovan Hendrych, and the most recent major taxonomic publications were made in 1994 and 1999 by
