Annual [perennial herb] or subshrub to shrub, 4–120(150) cm, generally aromatic. Stem: generally ± erect, generally ± solid. Leaf: proximal in basal rosette or opposite (generally not persistent), most alternate, sessile, linear to lanceolate or oblanceolate, proximal generally pinnately lobed to serrate, distal generally entire, hairy, often glandular. Inflorescence: heads radiate, generally in flat-topped or ± panicle-like clusters or in tight groups; involucre bell- or urn-shaped, hemispheric, or ± obconic, 2–13+ mm diam; phyllaries 3–35 in 1 series, ± linear to lanceolate or oblanceolate, each generally 1/2 enclosing a ray ovary, falling with fruit, ± hairy and sessile- or stalked-glandular; receptacle flat to convex, glabrous or minutely bristly; paleae in 1 series between ray and disk flowers in annual or in 2–3+ series or subtending all or most disk flowers in shrubs, fused or free, phyllary-like, more scarious. Ray flower: 3–35; corolla deep or pale yellow. Disk flower: 3–70, generally staminate, sometimes bisexual; corolla yellow, tube <= throat, lobes deltate; anthers generally ± red to dark purple or yellow to brown, tips lance-ovate to deltate; style glabrous proximal to branches, tips awl-shaped, densely bristly. Fruit: ray nearly round in ×-section (except ± flattened adaxially) or ± 3-angled (abaxially generally ± widely 2-faced, adaxially ± flattened to slightly bulging), generally ± arched, glabrous, tip ± beaked, beak offset adaxially, ascending, pappus 0; disk fruit generally 0, disk pappus generally of 1–15 generally linear to lanceolate, entire or fringed to deeply cut scales, sometimes 0 or crown-like.
21 species: California, western Arizona, northern Baja California. (Greek: fierce man, probably for name it replaced, Hartmannia DC., meaning "stag man," stags being fiercely territorial) [Baldwin & Strother 2006 FNANM 21:280–286; Baldwin 2007 Amer J Bot 94:237–248] Self-sterile except Deinandra arida and Deinandra mohavensis.
Unabridged disk flower: anther bases cordate-sagittate to sagittate.
