Capitula 2-3 mm, ovate or pyramidal, gathered in 2s-10s into numerous corymbs, arranged at apices of stems and ramuscules and forming paniculate, racemose, more rarely spiciform synflorescences; floral leaves as long as or shorter than capitula.

Achenes light brown, oblong-ovate, slightly flattened, 0.8-1 × ca. 0.3 mm, with sparse papillose hairs, larger than in other species of genus.
