Angianthus is an Australian genus of composite plants with compound flower-heads in which the involucres of the partial heads are compressed and composed of only a few bracts (Black & Robertson 1965).

Characters (from Black & Robertson 1965). Herbs with alternate entire leaves. Partial flower-heads numerous, few-flowered, crowded on a general receptacle in a dense compound terminal head; general involucre never conspicuous, consisting of a few empty basal bracts similar to those subtending partial involucres or of scarious bracts not longer than enclosed partial involucres, and concealed by floral leaves; partial involucres usually compresssed, consisting of two to several hyaline bracts, mostly opposite in pairs, outer involucres concave or conduplicate, inner involucres flat; flowers tubular, bisexual, yellow, usually five-toothed; anthers tailed; pappus various or absent.
