Socotra and the Dragon's Blood Trees

Tune in on the map One of 2,000 strange cases on a globe you can drag

On an island off Arabia grow trees shaped like upturned umbrellas that bleed red sap. Ancient people said it was the blood of a dragon.

What was reported

Socotra lies in the Arabian Sea between Yemen and Somalia, cut off from the mainland for millions of years. About a third of its plants grow nowhere else on Earth, so its landscapes look like another planet.

Its most famous tree, the dragon's blood tree, has a thick crown spreading like an umbrella and oozes a deep red resin. Ancient writers said it came from a battle between a dragon and an elephant, and the resin was traded as a medicine, a dye and a varnish.

Explanations offered

The island's isolation and harsh, dry climate led its plants to evolve along their own lines; the umbrella shape helps the trees catch moisture from mist and shade their roots. The red resin is still harvested. Socotra is a UNESCO World Heritage Site.
