Taraxacum britannicum

Taraxacum britannicum, commonly known as the British dandelion, is a perennial agamospermous species of dandelion in the family Asteraceae. It is native to northwestern and western Europe, with a primary distribution in the British Isles, where it occurs in a variety of habitats including wet meadows, cliffs, ravines, pavements, and other disturbed or man-made environments. The species is also reported from several other European countries, particularly in Western Europe and Fennoscandia. T. britannicum is morphologically variable, especially in leaf shape, and has often been considered a leaf-form variant of Taraxacum adamii. Despite historical recognition as a separate species, the two are now widely treated as conspecific, with shared floral and fruit characteristics and a tendency to co-occur with intermediate forms. The taxon was first formally described by Swedish botanist Gustaf Dahlstedt in 1927 in the Report of the Botanical Society and Exchange Club of the British Isles....read more on Wikipedia.
