| Description
| - Recent studies of the Alyssum montanum-A. repens complex in Europe showed that populations from central and southern Italy are, in contrast to previous taxonomic treatments, clearly distinct from A. montanum and should be classified as A. diffusum. Based on the high, geographically structured genetic variation (central Apennines, Gargano, and southern Apennines/Calabria) of A. diffusum, three subspecies were recently recognised. Here, we present a detailed morphometric study of A. diffisum in Italy, exploring its differentiation from A. montanum and differentiation among the three subspecies (A. diffusum subsp. diffusum, subsp. garganicum and subsp. calabricum). We report that A. diffusum differs from A. montanum subsp. gmelinii particularly by having (on average) larger flower parts and from subsp. montanum by a different density and morphology of trichomes and narrower petals. The subspecies of A. diffusum can be distinguished by the number of trichome rays, by trichome density on the lower leaf surface and by the leaf length. In this study, we present an identification key that includes the subspecies of A. diffusum, those of A. montanum and the related A. cuneifolium. We also provide detailed morphological descriptions of all three subspecies of A. diffusum and a nomenclatural account, including the designation of the lectotype of the name A. diffusum.
