Lycopersicon esculentum var. cerasiforme is the ancestral stock from which the large cultivated tomato (var. esculentum) was domesticated. Plants on Taiwan are probably feral populations that have regressed from cultivated var. esculentum rather than ancestral material.

台灣 : frequently occurring in disturbed areas in the south at low elevations.
世界 : Native to tropical America, plants of this variety are now nearly cosmopolitan.
