Achyrophorus Scopoli; Trommsdorffia Bernhardi.
Herbs, perennial or rarely annual, often rosulate, usually with rigid simple hairs. Stems solitary to few [or sometimes acaulescent], usually sparsely branched or more rarely simple, leafless or sparsely leafy. Synflorescence single-headed or weakly corymbiform with few to several capitula. Heads with ca. 20 to many florets. Involucre cylindric, narrowly campanulate, or broadly hemispheric. Phyllaries ± glabrous or hispid; outer phyllaries in several series, gradually longer centripetally, ± imbricate, often ca. 3/4 or more as long as inner ones; inner phyllaries ± linear-lanceolate to linear, ± equal in length. Receptacle with linear scarious scales ± as long as involucre and enclosing base of florets. Florets yellow or white. Achene mostly rather long, homomorphic or dimorphic; body cylindric to fusiform, with 5 muricate main ribs, with or without secondary ribs, with or more rarely without a slender to capillaceous beak often longer than body. Pappus white or dirty white, with all bristles stiffly fimbriately plumose or inner ones plumose and outer ones scabrid.
About 60 species: Asia, Mediterranean region, South America; six species (four introduced) in China.
