Ray-florets pistillate, ligulate, white to purple; disk-florets tubular, perfect or sts abortive. Anthers us. obtuse at base; style-arms of disk-florets flattened, with lanceolate-triangular unreceptive tips. Achenes compressed or rarely ± turgid, ± dimidiate to obliquely obovate, contracted to base; margins us. thickened; beak ± viscid, pappus 0.
