Abstract

Two diploid forms of Dactylis are known to occur on the Canary Islands, Dactylis smithii at low altitude and the newly discovered Dactyls metlesicsii at high altitude. Nuclear ITS sequences of these two diploid forms were compared with a wider set of diploids from Spain, Portugal and North Africa. The results suggest that Dactylis has a dual origin in these islands. The newly discovered high altitude form metlesicsii was found to have originated from the Iberian Peninsula unlike the low altitude form smithii which originated from nearby North Africa. It is also likely that hybrid forms occur where their ranges overlap.
