Phyllaries persistent, 17–21 in 2 series (outer usually distinct, sometimes connate proximally, green, narrowly elliptic to lanceolate, herbaceous, moderately to densely pilose, especially bases and margins; inner phyllaries distinct, obovate, hyaline, scalelike, glabrous). Receptacles globose to ovoid, ± pitted, usually epaleate (outer disc-florets rarely subtended by paleae, central disc-florets usually subtended by persistent enations). Ray-florets 8–13 (–20), pistillate, fertile; corollas yellow.
