    blades (3-nerved) lanceolate to broadly ovate, margins entire or serrulate to serrate, faces glabrate to densely pilose.
    Heads radiate or discoid, in ± cymiform arrays.
    Involucres hemispheric to campanulate, 2.5–6 mm diam.
    Phyllaries persistent or falling, 6–9 [–16] in 2 [–3] series (elliptic, lanceovate, oblong, or ovate, outer shorter, herbaceous or scarious, margins entire or minutely laciniate).
    Receptacles conic, paleate (paleae persistent or falling, scarious, proximal broadly elliptic to obovate, often connate at bases or nearly to apices, united in groups of 2–3 to adjacent proximal phyllary, each complex often enclosing and shed with a ray cypsela; distal persistent or falling, lanceolate to obovate, entire or 2-lobed or 3-lobed, convex to conduplicate).
    Ray-florets [0–] (3–) 5 (–8) [–15], pistillate, fertile;
    corollas white or dull white to pinkish [purplish] (tubes pilose, laminae quadrate-obovate to oblong, lobes 0–3).
    Disc-florets 5–50 [–150], bisexual, fertile;
    corollas yellow, tubes (pilose) shorter than cylindric throats, lobes 5, deltate (anthers yellow; style-branch apices acute).
    Cypselae obconic to obpyramidal, glabrous or strigose (rays often shed with subtending phyllary plus 2–3 adjacent paleae);
    pappi 0, or persistent, of 5–20, white or gray, fimbriate, sometimes aristate scales.
