Herbs, shrubs or undershrubs, mostly arachnoid, white woolly or glandular. Leaves alternate or subopposite, entire or lobed or dentate. Inflorescence mostly paniculate or spiciform. Heads discoid or seldom radiate, homogamous or heterogamous, small, dioecious in some genera. Involucral bracts sometimes coloured, many in several graded series, overlapping, often glistening. Receptacle flat or convex, paleaceous or epaleaceous. Ray florets with slender, filiform or ligulate corolla, minutely toothed. Disc florets usually light yellow or white, with tubular, campanulate corolla, 4-5 lobed. Anthers connate, apically appendaged, tailed at base. Style branches various, apically rounded or truncate, ovaries mostly terete. Achenes flat, terete, angled or elongated, usually very small, often ribbed. Pappus of many fine, strigose bristles or absent.

A cosmopolitan tribe usually abundant in old world regions, particularly Australia and S. Africa; about 300 genera and ca 2000 species, 25 genera and 147 species in India.

Notes. The generic limits in Inuleae are often not very distinct. Morphologically this tribe is similar to Astereae. Some of the most distinguishing characters of Inuleae are: strongly tailed anthers, flattened style, branches with marginal stigmatic lines and mostly capillary pappus. Cytologically this tribe is not well known. The known base numbers of gametic chromosomes are 5, 7, 8, 9, 10, 11.
