Taxon discussion

Α new subspecies for the Greek flora. Hesperis matronalis is a widespread and variable species divided into 6 or 7 subspecies, of which subsp. Hesperis matronalis cladotricha ( Borbás) Hayek has been recorded as a rare plant of the Mt. Timfi area in north-west Greece ( Goulimis 1960, Ganiatsas 1971, Authier 1993, Bergmeier 2008). Our collection from NE Greece (Fig. 13) presents a monomorphic indumentum on upper and lower leaf surfaces consisting of simple eglandular hairs; branched hairs are very scarce and rarely found along veins and margins. It clearly fits subsp. Hesperis matronalis matronalis because of its unbranched hairs, pink-purple flowers and petiolate middle and upper stem leaves. In contrast, a specimen of subsp. Hesperis matronalis cladotricha examined (Κ. Goula & Ν.Α. Katsaros 3036, Mt Timfi, Skamneli, ATHU!) presents an indumentum of predominantly bifurcate (and occasionally trifurcate) eglandular hairs; simple hairs are very rare or absent. Hesperis matronalis is present in all the floristic regions of neighbouring Bulgaria ( Assyov and Petrova 2012) and, therefore, its occurrence in NE Greece was to be expected. The Greek population grows in a very natural habitat away of any human interference and is clearly indigenous. Interestingly, a Greek collection of subsp. Hesperis matronalis matronalis already appeared amongst the specimens examined by Duran and Ocak (2005) from Mt. Pangeo (Pangaeo, west of Kawala, Fagus forest, 3500 ft., J.D.A. Stainton 7737, 21.06.1959, K), but this record has passed unnoticed (Fig. 7 ).
