There are several figures of it among the older botanists, but not one that does it any justice, as an ornamental green-house plant, which it undoubtedly is, and continues in bloom almost from June till January. Our figure represents the entire plant, just as we received it from Messrs. Whitley and Brames. [Illustration] PLATE DLVIII. FERULA PERSICA. _Persian Ferula._ CLASS V.
