Clypeola L., Sp. Pl.: 652. 1753.
Tribe: Alysseae DC.
Notes. – The genus includes nine Eurasian-NW African species distributed from Morocco and Spain eastward into Uzbekistan (ŠPANIEL et al., 2015).
Although it was united earlier by AL-SHEHBAZ (2013) with Alyssum, the current evidence at hand strongly supports the maintenance of both genera.
