The stem-leaf is bract-like or absent, or egg-shaped, long-pointed, toothed low down, stalked. The panicle is a falsely-forked corymb. The stalks are straight or ascending, woolly-felted, glandular. The 3-8 heads are broad, egg-shaped. The phyllaries are broad, lance-shaped, linear, blunt, folded in early bud, woolly-felted at the margin, senescent, the inner narrow above, with many yellow glandular hairs.

The stem-leaf is wanting, or solitary, linear, lance-shaped, stalkless. The lower branches are nearly erect, the upper ascending and exceeding the acladium. The stalks are woolly-felted, glandular, with few hairs. The 3-6 heads are large, round or broad to egg-shaped. The phyl-laries are bent inwards, but do not meet together in bud, rather broad, oblong, linear, narrow above, blunt, the intermediate narrow, acute, woolly-felted at the edge, hairy, glandular.
