drias

“The plant, which is elaborately described by Theophrastus, appears to have been successfully identified by modern travellers in the Cyrenaica, who see it in the drias or derias of the Arabs, an umbelliferous plant, which grows to a height of about three feet, has a deleterious effect on the camels that browse on it, and bears a striking resemblance to the representations of the ancient silphium upon coins and medals.”
