Abstract

Noccaea cadinensis sp. nov. is described here. This species is known from a single locality in Serra del Cadí (Eastern Pyrenees, SW Europe), where it grows in limestone scree and stony meadows of the alpine vegetation belt. It is morphologically close to N. nevadensis from Sierra Nevada (S Iberian Peninsula), from which it can be separated by several characters (fruit length, style length, corymb elongation, petiole length, leaves margin, seed size). The new species is assessed as EN (Endangered) according to IUCN Red List Categories and Criteria.
