Adoxa moschatellina subsp. cescae subsp. nova is proposed. Phytogeographical, karyological and morphological evidences are presented. This subspecies appear to be endemic to the Coastal Chain, Calabria (S Italy) and shows a triploid (2n = 54) chromosome complement, different from the diploid (2n = 36) one of A. moschatellina s.s. By a morphological point of view, pollen and stomata size of the latter (from the whole Italy, including the Pollino Massif, N Calabria) appear to be smaller in average than those of the new subspecies, which can be considered as a new apoendemic taxon, because of its distribution and high ploidy level.
