Anagallis arvensis subsp. foemina
This subspecies is normally found as an arable weed and appears to be absent from the semi-natural habitats in which subsp. arvensis occurs. Lowland.
The blue-flowered subsp. foemina and the blue-flowered variant of subsp. arvensis, forma azurea (also mapped by Perring & Sell, 1968), have long been confused. Subsp. foemina may be declining, probably due to more intensive weed control in arable fields, but the 1968 map only included confirmed records so it is difficult to assess changes in distribution. Some recent records might be of bird-seed aliens.
As an archaeophyte subsp. foemina has the Eurosiberian Southern-temperate distribution of the species, but its distribution is more southerly than subsp. arvensis.
