The cutleaf groundcherry (Physalis angulata) belongs to Solanaceae (the Nightshade family). It is an anuual herb that is native to southern North America, but is now widely distributed and naturalized in tropical and subtropical regions worldwide. This herb is erect, much branched, and grows up to a height of 80 cm. The leaves are dark green, roughly ovate, often with irregular toothed edges. The flowers are five-sided and pale yellow with brownish throat, and bloom from July to October. After flowering, the yellow-orange fruits are born inside a balloon-like calyx. The calyx has 10 ridges which are green at first and turn purplish brown when mature.
