Galapagos Islands plantlife - transitional zone flora
It is intermediate in character between the scalesia and arid zones, 
but dominated by different species than either of the adjacent zones. The forest is still mainly deciduous. It is much more dense and diverse than forest of the arid zones and it is often difficult to say whether any species is dominant.
Rising up the island plants become more frequent. In the Transition Zone plants from both the Arid
Lowlands and the Upper Moist Zones occur. This zone is home to a variety of small trees or shrubs including the endemic Pega Pega Tree and the endemic Guayabillo, which produces a small white flower that develops into a fruit similar to its cousin the Guava.
The Galapagos Tomato, endemic to the islands is a salt resistant tomato that has been used to create a hybrid, which is capable of growing in salty soil around the world
