Despite the morphological similarities between P.ixocarpa and P. philadelphica, these are different species. The former is distinguished from the latter by a capitate stigma, and relatively smaller flower and fruit (Fernandes 1974; Hanelt and IPK 2001).
Physalis peruviana is a South American plant native to Colombia, Ecuador and Peru in the nightshade family (Solanaceae), commonly known as Cape gooseberry or goldenberry, known in its countries of origin as aguaymanto, uvilla or uchuva. (https://en.wikipedia.org/wiki/Physalis_peruviana)
