Annuals or perennials [subshrubs, shrubs, or trees]. Leaves basal and/or cauline (basal often withering before flowering); alternate [opposite]; petiolate or sessile; margins entire or dentate to serrate [pinnately divided]. Heads heterogamous (radiate [disciform]) [homogamous (discoid)], usually in corymbiform, paniculiform, or racemiform arrays, sometimes borne singly (on ± leafy stems). Calyculi 0. Phyllaries persistent [falling], in (2–)3–7+ series, distinct, unequal to subequal, herbaceous to chartaceous or membranous, margins and/or apices usually scarious. Receptacles flat to convex [concave], epaleate [paleate]. Ray florets [0] in 1(–2+) series, pistillate and fertile [neuter]; corollas usually yellow, sometimes reddish [ochroleucous or purplish] (laminae often linear). Disc florets bisexual, fertile; corollas usually yellow, sometimes reddish [ochroleucous or purplish], not 2-lipped, lobes (4–)5, usually ± deltate; anther bases ± tailed, apical appendages ovate to lance-ovate or linear; styles abaxially glabrous or papillate (distally), branches ± linear, adaxially stigmatic in 2 lines from bases to apices (lines often confluent distally), apices rounded to truncate, appendages essentially none. Cypselae usually monomorphic within heads, usually ellipsoid or columnar to prismatic [compressed or obcompressed], not beaked (sometimes abruptly constricted at each end), bodies often ribbed (glabrous or hairy, often glandular, hairs not myxogenic); pappi persistent (fragile), of ± barbellate [plumose] scales (sometimes setiform or aristate) and/or bristles.
Distribution
Introduced; Old World, especially Eurasia and n Africa, some species widely introduced and established in local floras.
Discussion
Genera ca. 40, species ca. 500 (3 genera, 5 species in the flora).
Following A. A. Anderberg (1994) and others, some 180 genera and 2000 species have been segregated from traditionally circumscribed Inuleae as Gnaphalieae, and another 25+ genera and 200+ species as Plucheeae.
