Anagallis

For the 2nd century BC grammarian sometimes thought to be named Anagallis, see Agallis.
Anagallis is a genus of about 20–25 species of flowering plants in the myrsine family Myrsinaceae, commonly called pimpernel and perhaps best known for the Scarlet pimpernel referred to in literature.

These are annual or perennial plants, growing in tufts on weedy and uncultivated areas. The stems are prostrate with ovate to cordate leaves. The flowers of the different species show miscellaneous colors. They are radially symmetrical with five petals. They grow usually in the leaf axils, but sometimes as short spikes at the top of the stem. Pimpernel flowers remain open only under direct sun-light.

They were formerly classified as members of the primrose family (Primulaceae), but a genetic and morphological study by Källersjö et al. (1999; see references) showed that they belong to the Myrsinaceae. Another study by Ulrika Manns and Arne A. Anderberg (2005), based on molecular phylogeny, states the genus in its present circumscription is paraphyletic and should also include in its clade the small genera Asterolinon and Pelletiera, as well as two Lysimachia species (Lysimachia nemorum and Lysimachia serpyllifolia).
