System

The species was first published in 1827 by Barthélemy Charles Joseph Dumortier as Alsine pallida. The combination as Stellaria pallida was a long time Louis Alexandre Henri Joseph Piré (1863 ) attributed to, but it has been found that this is invalid and only by François Crépin (1865 ) was validly published. The bleach bird chickweed was once considered a subspecies of the closely related bird chickweed ( Stellaria media ) and as Stellaria media subsp. pallida ( Dumort. ) Asch. & Graebn. referred to.
