Description
Eriophyllum is an annual or perennial shrub or subshrub, some species growing to a height of 200 cm (6.7 feet). Leaves present generally alternate and entire to nearly compound, with woolly hairs on some of the species. The inflorescence contains numerous yellow flower heads in flat-topped clusters. The involucre structure is obconic to hemispheric. Phyllaries are either free or more or less fused; the receptacle presents typically flat, but naked. The ray flowers are present in some species but not in others. Fruits are angled in the outer flowers, but are generally club-shaped for the inner flowers; the pappus is somewhat jagged.[6][7]
