XVI International Botanical Congess
The Inuleae contain 36 genera distributed in the Old World. The tribe has a number of endemics in the Macaronesian Archipelagos, including three genera (Allagopappus, Schizogyne, and Vieraea) endemic to the Canary Islands and several endemic species in the genera Asteriscus and Pulicaria. We have constructed molecular phylogenies for 45 taxa using sequences from the nuclear ITS region and the chloroplast gene ndhF. Trees from these markers are largely congruent and provide several insights into the origin of the island endemics, including multiple colonizations of the islands not only for the tribe but also for the two endemics of Pulicaria from the Cape Verde and Canary Islands.
