Alyssum calycinum Linnaeus, Species Plantarum, ed. 2, 2: 908. 1763, nom. illeg.

"Habitat in Austria, Gallia, Germania." RCN: 4734.

Replaced synonym: Clypeola alyssoides L. (1753) .

Lectotype (Dudley in J. Arnold Arbor. 45: 63. 1964): Herb. Clifford: 329, Clypeola 2 (BM-000646255) .

Current name: Alyssum alyssoides (L.) L. ( Brassicaceae).

Note: As noted by Dudley (in J. Arnold Arbor. 45: 65. 1964), this is an illegitimate replacement name for Clypeola alyssoides L. (1753) . However, Botschantzev (in Novosti Sist. Vyssh. Rast. 15: 150-151. 1985) incorrectly treats it as the correct name for C. alyssoides and C. campestris L. (1753), both of which he treats as ambiguous. See further notes on this name by German (in Turczaninowia 6(1): 53-55. 2003).
