Chi Physalis - Physalis minima L. – Thù lù nhỏ

Physalis (/ˈfaɪsəlɪs/, sometimes /faɪˈseɪlɪs/)^[2] is a genus of plants in the nightshade family (Solanaceae), which grow in warm temperateand subtropical regions of the world. Most of the species, of which there may be 75-90, are indigenous to the New World with one notable exception (P. alkekengi). Cultivated species and weedy annuals have been introduced worldwide. A notable feature is the formation of a large papery husk derived from the calyx, which partly or fully encloses the fruit,.^[3] The fruit is small and orange, similar in size, shape and structure to a small tomato.

At least 46 species are endemic to the country of Mexico.^[4]

Many Physalis species are called groundcherries.^[5] One name for Physalis peruviana is Cape gooseberry, not to be confused with the true gooseberries, which are of the genus Ribes in the family Grossulariaceae.

As of 2005, about 75 to 90 species were in the genus.^[3]
