Taraxacum angulare Hagend., Soest & Zevenb. “Angular-lobed Dandelion”
Introduced. A scarce casual with records from much of Britain. Waste places, verges, paths, gardens etc.
A medium-sized dandelion with suberect ovate-lanceolate leaves of a rather shiny mid-green. Petioles winged, rather long, white on outer leaves, pink on inners. Leaves notably heterophyllous, the outer with 4-5 regular triangular side-lobes with one tooth on the distal margin and a small triangular end-lobe; inner leaves with 3-4 spaced, patent lobes often interspersed with one lobule and a large rounded end-lobe subdivided by 1-2 shallow teeth on each side, giving the end-lobe an angular appearance. Exterior bracts rather short, 12 x 3 mm, slightly recurved, pale green, slightly bordered. Ligules with a dark violet stripe below. With its strongly heterophyllous leaves with white outer petioles and pink inners, T. angulare is reminiscent of T. ekmanii, but the shiny leaves are darker in colour and the angular end-lobe of inner leaves is distinctive. Nevertheless, this is not an easy dandelion to identify, is not well understood, at least in the British Isles, and may be underrecorded.
