Description: Herbaceous annual 15-45 cm (6-18 in) tall, commonly hairy, with branched leafy stems.  Thin translucent leaf-blades range from ovate to broader than long, 5-7 cm (2-2.8 in) long, with or without a few teeth; the leaf-stalk is about as long as the blade.  Petiles are 1.5-7 cm (0.6-2.8 in) long.  Solitary flowers with calyces 3-4 mm long with lobes about half that long on lateral peduncles that are 3-8 mm long.  The yellow corollas are dark-spotted and small, 4-6 mm long. Fruiting calyces with sparsely appressed hair, strongly 5-angled, 2.5-4 cm long and 3-4 cm wide.  Fruiting berry globose, seeds many and flat.

Etymology: Physalis comes from the Greek physalis, "a bladder or bubble," because of the inflated calyx, while the meaning of latiphysa is partially from the Latin latus for broad, and the Greek physa or bellows for the bladdery fruit.
