About Lysimachia tenella L.
Lysimachia tenella L., with the synonym Anagallis tenella, is commonly called bog pimpernel in Britain. It is a low-growing perennial plant that grows in a range of damp habitats, including calcareous dune slacks, boggy areas, and peaty heaths. Its native range covers western and southern Europe, as well as Northwest Africa. In the United Kingdom, the species is now mostly restricted to the western half of the country. It was more widespread in eastern Britain before land drainage and agricultural intensification reduced its populations there. Carl Linnaeus first formally described this species as Lysimachia tenella in 1753. Later, the species was moved to the genus Anagallis. After molecular phylogenetic research showed that Anagallis should be synonymized under Lysimachia, this species was moved back to the genus Lysimachia. The Latin specific epithet tenella translates to "tender" or "delicate". In England, this plant is one of the species found in the Purple moor grass and rush pastures BAP habitat.
