Clusia rosea

autograph tree

A fifteen foot tall hedge of autograph trees, Clusia rosea, on the border of the beach at The Botanic Gardens at Kona Kai Resort in Key Largo, Florida

This plant is known as the autograph tree because its leaves are so thick, one can inscribe on them with a pointed implement. Spanish soldiers used these leaves as notepaper and makeshift playing cards. The plant is also known as pitch apple because the sticky black substance surrounding the seeds was once used to caulk boat seams.
