Pseudodictamnus mediterraneus subsp. lycius (Hub.- Mor.) Raus , comb. nov.

≡ Ballota pseudodictamnus subsp. lycia Hub.-Mor. in Bauhinia 2: 203. 1963.

– From a phylogenetic analysis based on nuclear and plastid DNA sequences representing all genera of the tribe Marrubieae, Siadati & al. (2018) revealed the necessity of splitting the genus Ballota L., in its traditional concept, into two well-supported clades matching well with the genera Ballota s.str. (2 or 3 species, with calyx limb regularly dentate, 5-toothed) and Pseudodictamnus Fabr. (13 species, with calyx limb undulate or crenate or irregularly dentate with 10 to many teeth). In this context, 13 new names and combinations in Pseudodictamnus at specific rank were proposed, among them P. mediterraneus Salmaki & Siadati ( Siadati & al. 2018: 779), known as Ballota pseudodictamnus (L.) Benth. in previous floristic literature. This is an E Mediterranean geoelement with its nominate subspecies P. mediterraneus subsp. mediterraneus (≡ B. pseudodictamnus subsp. pseudodictamnus ) distributed in the S Aegean area (Crete and Andikithira, see Strid 2016: 537, map 2116), extending to opposite N Africa (Cyrenaica, Patzak 1959: 52; POWO 2023), and a second subspecies occurring in SW Asia ( Stapf 1885: 41; Davis & Doroszenko 1982: 157–158), originally described as B. pseudodictamnus subsp. lycia Hub.-Mor. , which differs mainly by its larger calyx limb with more prominently mucronate teeth ( Huber-Morath 1963: 203). For the latter, a still lacking name under Pseudodictamnus is proposed here. Th. Raus
