Common cat's-ear Hypochaeris radicata, from here.

Belongs within: Cichorieae.

The Leontodontinae contains the hawkbits and related plants. They are distinguished from other subtribes in the Cichorioideae by their pappus of plumose bristles, rather than scales or capillary bristles. The receptacle bears chaffy scales in Hypochaeris, cat's-ears, but is naked in other genera (Black & Robertson 1965). Tragopogon porrifolius (salsify) and Scorzonera laciniata (scorzonera) are grown as root vegetables.

Characters (from Black & Robertson 1965): Flower-heads homogamous, flowers all bisexual; style with plano-convex branches attenuated towards summit, bearing stigmatic papillae on whole of inner and well-developed collecting hairs on outside down to below place where branches fork; anthers acute or acuminate at base; pappus of plumose bristles.
