Euphorbia tirucalli


 Euphorbia tirucalli Indian tree spurge

Árbol de los dedos

This toxic shrub is native to Africa and the Arabian peninsula. I found it growing in the stone desert near to Albaricoques Almería. It may have naturalised as it is a semi-arid plant from tropical regions. It produces latex which can be converted to gasoline. It is extremely toxic to the skin and mucosa. Deaths have occurred due to people swallowing the latex.
