 seeds remain distinct from each other but separated from the seeds forming two membranous plates between the seeds, or remaining attached to the nucleus or to the whole seed leaving the seeds separate, each with a double or wingle wing.&mdash;Shrubs, often low or flowering near the base. Leaves alternate, very rarely entire, usually either sinuate and prickly-toothed, or pinnatifid or pinnate with numerous small regular lobes or segments, usually smooth and veinless on the upper surface, white-tomentose or marked with parallel transverse veins underneath. Flowers sessile, in pairs, in dense terminal or lateral heads in an involucre of numerous imbricate scale-like bracts and usually surrounded by a ring of floral leaves similar to the stem leaves; receptacle flat or convex, densely villous or woolly, with narrow-linear villous or woolly bracts or paleæ subtending each pair of flowers, sometimes very small or deficient at least in the centre of the head. Perianth usually yellow, the short entire base glabrous or villous towards the divided part, the remainder of the tube or claws usually pubescent or villous, the limb occasionally, the whole perianth very rarely, glabrous. Ovary almost always hairy. Capsules usually villous, but the hairs very readily rubbing off, and in some species apparently glabrous from the first.
