Herbs, perennial, rarely subshrubs. Leaves alternate, often in basal rosettes or densely aggregated near median part of stems; blade linear, ovate, elliptic, or orbicular, margin entire, crenate, denticulate, dentate, or lobed. Capitula many in spikes, racemes, or panicles, sometimes nodding, radiate or discoid, homogamous; involucres cylindric; phyllaries often multiseriate, imbricate; receptacle small, glabrous, epaleate. Florets few, (1-)3(-5), bisexual, all fertile, chasmogamous or cleistogamous; chasmogamous corollas open, deeply irregularly 5-lobed, one of slits much longer than others, lobes linear, reflexed and usually coiled; cleistogamous corolla (if present) closed, tubular, shorter than pappus; anther bases long tailed, apex appendages truncate to rounded, sometimes apiculate; styles shallowly divided at apex, style branches short, abaxially with papillae, apices obtuse to acute, rounded, or truncate. Achenes terete or fusiform, ribbed, glabrous or pilose; pappus of plumose bristles or sometimes absent in chasmogamous florets, usually uniseriate, more rarely biseriate. 2n = 24, 26.
