Leontodontinae

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


Belongs within: Cichorioideae.

The Leontodontinae contains the hawkbits and related plants. They are distinguished from other subtribes in the Cichorioideae by their pappus of plumose brsitles, rather than scales or capillary bristles (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.
