It is thought that some of the plants that grow on the rocky islands of Lake Valencia are exclusive to them because they have not been discovered elsewhere. Among these are the papaw tree of the lake (papaya de la laguna), and a tomato (81) from Cura Island; this differs from our Solanum lycopersicum in that its fruit is round and small but very tasty. The papaw of the lake is common also on Cura Island and at Cabo Blanco. Its trunk is slenderer than the ordinary papaw, but its fruit is half the size and completely round, without projecting ribs. This fruit, which I have often eaten, is extremely sweet.
