Inula (ancient name). Compositae. Hardy herbaceous plants of the easiest culture and of rather coarse habit, with heads of yellow or orange, each 2 to 4 inches across, borne in summer. Herbs, usually perennial, glandular, hairy : lvs. radical or alternate, entire or serrate: heads large, medium or small, solitary, corymbose, panicled or crowded at the crown; fls. tubular and ray, the rays yellow, rarely white; disk-fls. perfect, their tubular corollas 5-toothed: achenes 4-5-ribbed. — A genus of about 56 species, found in Eu., Asia and Afr. None of its near allies is cult. There is such a great abundance of autumn-flowering yellow composites in the hardy border that only those inulas that bloom in early summer are particularly desirable. Elecampane, I. helenium, is probably also cultivated for medicine. A preparation of the mucilaginous roots is common in drugstores. Inula flowers have as many as forty linear rays. The plants like a sunny position, grow vigorously in any garden soil, and are propagated by division or seed. I. oculus-christi. Linn. Two ft.; an erect, somewhat branched, woolly perennial with oblong hairy lvs.: fls. yellow, the rays twice longer than the involucral bracts. Sold in England, but apparently unknown in Amer.
