"[Plin. Nat. 22.42.] - THE SILLYBUM.
The sillybum resembles the white chamæleon, and is a plant quite as prickly. In Cilicia, Syria, and Phœnicia, the countries where it grows, it is not thought worth while to boil it, the cooking of it being so extremely troublesome, it is said. It is of no use whatever in medicine.”
