Taraxacum akteum

Taraxacum akteum, sometimes referred to as the Hampshire dandelion, is a rare and geographically restricted species of dandelion in the family Asteraceae. It is endemic to parts of Western Europe, occurring only in Great Britain and the coastal regions of the Netherlands. The species was first described in 1974 in Acta Botanica Neerlandica from specimens collected in slightly brackish meadows at Doornspijk and Rozenburg by Hagendijk, van Soest, and Zevenbergen. It belongs to the section Taraxacum section Celtica, a group of microspecies adapted to grassland habitats. T. akteum is most often found in temperate flood-meadow environments, where it grows in low-competition, seasonally moist soils. Its narrow ecological range and distinct morphology make it an uncommon and under-recorded member of Europe's dandelion flora....read more on Wikipedia.
