Stipules spinescent; no “ant-galls.” Flower-heads not panicled; involucel normally at or below middle of peduncle. Flowers white, pink, cream or greenish; corolla-lobes ± densely white-pubescent outside. Pods dehiscent, sometimes slowly so, straight or annular, often thick hard and woody, ± densely clothed with very short to rather long hairs, sometimes wing-margined.
