Solanum vestissimum

Also known within its native range as toronjo, tumo, or coquina melón, S. vestissimum is a large semi-woody plant or shrub, up to 8 meters in height, though usually much smaller.

The very large heart-shaped leaves are lined with spines along the top and bottom of the dorsal vein, similar to the naranjilla or pseudolulo.

Native to temperate, cloud forest zones of Colombia and Venezuela, the toronjo bears edible fruit, but is rarely cultivated.

The strong, sweet-tart flavor is regarded as excellent, and worthy of further agricultural investigation, but the fruit is also covered with sharp bristles which persist upon full ripening, and which can be irritating to the skin Unharvested fruit will often swell and burst, releasing seeds.

[1] Specimens of each of these plants are often spiny, covered in short hairs, and share a similar leaf shape; many of them bear edible fruit, and hybrids between many of these species are possible.
