The Dragon's Blood tree is one of Socotra's iconic natural features. These trees grows in droves high up on Diskum plateau in the center of the island, each one a mathematical object, with bifurcating branches obeying obscure yet graceful laws of mathematics. 

I got to this spot by getting off the main road, driving along a very rocky track for for a while, then getting out of the car and heading straight into the bush. The underbrush conceals all manner of interesting life — lizards, strange-looking spiders — and the going was slow, but the resulting immersion in Socotra's exotic nature was well worth the effort.
