#habitat indicator
- Anagallis tenella — The scientific name of a perennial herbaceous plant in the family Primulaceae (currently classified as Lysimachia tenella), native to Western and West-Central Europe, where it inhabits wet habitats such as bogs, fens, and stream banks. The plant is structurally characterized by extremely thin and delicate creeping stems, small rounded opposite leaves, and funnel-shaped flowers of a delicate pale pink with darker veins, serving as an important ecological indicator for water-saturated acidic soils.
