Note. – The previous and following pairs of entries have long been fluctuating between the genera Alyssum and Meniocus, but from ŠPANIEL et al. (2015) onward, the latter genus is firmly established on solid morphological and molecular grounds. It is readily distinguished from Alyssum by having 2–4(–8) vs 2 ovules per locule on parietal vs apical or subapical placentae.
