The iasione2252 has a single leaf only, but that so folded and involved, as to have all the appearance of being several in number. The chondrylla2253 is bitter, and the juice of the root is of an acrid taste. The aphace, too, is bitter, and so is the plant called “picris,”2254 which also remains in flower the whole year through: it is to this bitterness that it is indebted for its name.2255
