Annuals, (1–) 2–10 (–30+) cm (taprooted, often stoloniferous and/or mat-forming). Stems 1–5+, ± procumbent to erect, simple or branched, glabrous or strigillose to villous [piloso-hispid] (hairs mostly basifixed). Leaves basal or basal and cauline; alternate; sessile or petiolate (bases ± clasping); blades ± obovate to spatulate, usually (1–) 2–3-pinnately or -pinnati-palmately lobed (ultimate lobes oblong or lanceolate to oblanceolate or spatulate), ultimate margins entire or dentate, faces glabrous or strigillose to villous. Heads disciform, borne singly (sessile in leaf-axils). Involucres ± hemispheric or broader, 2–8+ mm diam. Phyllaries persistent, 5–8+ in 1–2+ series, distinct, lanceolate to ovate, subequal, margins and apices (usually colorless, sometimes brownish) scarious. Receptacles flat to hemispheric or conic, epaleate. Ray-florets 0 (peripheral, pistillate florets 5–100+ in 1–8+ series; corollas 0, styles sheathed by pericarp tissues, soon indurate, becoming spinelike). Disc-florets 2–8+, functionally staminate; corollas yellowish or whitish, tubes ± cylindric, throats campanulate to funnelform, lobes (2–) 4, ± deltate (without resin sacs). Cypselae: (bodies) ± obovate to oblanceolate or oblong-cuneate, obcompressed or flattened, winged (wings entire or sculpted), faces glabrous or ± scabrellous to hirtellous or (distally) villous to pilose or arachnose, glabrescent (pericarps without myxogenic cells or resin sacs); pappi 0 (persistent stylar sheaths indurate, spinelike). x = unknown.

Distribution
