Groundcherry + Yam

Physalis is a genus of plants in the nightshade family (Solanaceae), native to warm temperate and subtropical regions of the world. All but one species are native to the New World, and most species occur in Mexico in particular. At least 46 species are endemic to the country. The genus is characterised by the small orange fruit similar in size, shape and structure to a small tomato, but partly or fully enclosed in a large papery husk derived from the calyx. Many Physalis species are called groundcherries. 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.

Yam is the common name for some plant species in the genus Dioscorea (family Dioscoreaceae) that form edible tubers. These are perennial herbaceous vines cultivated for the consumption of their starchy tubers in Africa, Asia, Latin America, the Caribbean and Oceania. There are many cultivars of yam. Although some varieties of sweet potato (Ipomoea batatas) are also called yam in parts of the United States and Canada, it is not part of the family Dioscoreaceae; rather it is in the morning glory family Convolvulaceae.
