Description:
Herbs usually with 1 or more thickish basal stems beating large leaves, from which arise sympodially 1 or more leafy flowering stems; cauline leaves opposite or alternate, dissected, lobed or toothed.
Flowers paired or solitary with 4 or 2 bracteoles at the base of the pedicels or along the length of the peduncle; stamens all bearing anthers (or rarely, but not in S. Aust., only 5 fertile); filaments broad, free or connate at the base, with 5 glands alternating with the petals.
Mericarps dehiscing so that the seed is exposed; awn curved or coiled towards the top, glabrous inside; hairs often present at the base of the funicle. 250-300 species mostly temperate but extending onto tropical mountains.
