Solanum cajanumense
 Solanum cajanumense (also known as casana) is a species of plant in the Solanaceae family. It is found in Colombia Ecuador and Peru. Intolerant of heat frost or direct sunlight Solanum cajanumense seems to prefer cloud forest-type growing conditions which limits its future agricultural potential. As with most solanaceae most parts of the plant are toxic but casana produces an edible yellow fruit similar in appearance to but smaller than the closely related tamarillo.
