Sharp-leaf Ground-cherry

Physalis acutifolia is an annual herb in the nightshade family, Solanaceae. It is native to the southwestern United States, including California, Arizona, Texas, and northern Mexico. The plant grows up to a meter tall with branching stems and leaves that are lance-shaped to oval, up to 12 cm long, with shallow, smooth teeth along the edges. The herbage is covered in thin, appressed hairs. Flowers are white to pale yellow, with bright yellow centers, and grow in the leaf axils. Each flower has five stamens with anthers about 3 mm long. The calyx expands as the fruit develops, forming a ribbed, lantern-shaped structure about 2 cm long that encloses the berry.
