Very similar to
Cat’s-ear (Hypochoeris radicata) from which it differs in its hairless or almost hairless leaves and its smaller flowers. Smooth Cat’s-ear belongs to a group of mainly yellow-flowered daisies in the Tribe Lactuceae. The plants in this tribe are characterised by having a basal rosette of leaves (flat-weeds), milky sap in their stems and their flower-heads consisting entirely of ray florets (i.e. no ‘eye’ to the daisy). See Key to Yellow Daisy Flat-weeds.
