| Résumé : |
"Melica (Poaceae) consist of about 92 species distributed across temperate regions of the world. Within section Dalycum, Melica ciliata sensu lato forms a taxonomic complex of several species and subspecies with clinal morphological variation causing conflicting identifications. To resolve taxonomic confusion, we employed three complementary approaches, through molecular, morphological and phytoecological analyses. The double‐digest restriction associated DNA markers significantly support the monophyly of three taxa: (i) the Mediterranean M. magnolii, (ii) the Eurasian M. transsilvanica subsp. transsilvanica and (iii) the west‐European M. ciliata subsp. glauca. This differentiation is corroborated by the analysis of 22 morphometric variables. Furthermore, phytoecological analysis of 221 floristic inventories revealed habitat distinctions among these taxa. Our approach of integrative taxonomy argues for a specific distinction for these three taxa, and we include a key to separate these forms. This new molecular data on the section Dalycum, subsection Ciliatae, calls for further phylogenetic analyses including samples of M. ciliata subsp. ciliata and other East‐Mediterranean and South African taxa.
