The Dracaena cinnabari is a dragon tree native to Socotra, an archipelago in the Indian Ocean.
A unique aspect of this species is that it’s an endemic species.
Endemism- the ecological state of a species being unique to a defined geographic location
Because the island of Socotra, Yemen, is a very arid place with low amounts of soil, the dragon blood tree’s shape is its main adaptation to its survival. The crown shape of its upper hemisphere provides shade, while simultaneously reduces evaporation. It also grows in the mountains where there isn’t a lot of space, so the trees grow very close together; the crown shape provides shade that aids in the survival of seedlings growing beneath the adult tree.
