Dendrosenecio kilimanjari, the giant groundsel that lives atop of Kilimanjaro in East Africa started its botanically described life as a species of the genus Senecio but has since been reclassified to be in its own genus Dendrosenecio, and always in the family Asteraceae. Recent biogeographic interpretation of the molecular phylogeny of the collected specimens of the giant groundsels suggests that about a million years ago, the first Senecio established themselves atop of Kilimanjaro. Those that survived the extreme daily conditions found at the heights of that young mountain adapted and became the species we now know as Dendrosenecio kilimanjari. Seeds from this species found a way to the other mountains (but not via wind dispersal which for Senecio and perhaps the whole family Asteraceae is measured in meters and not kilometers), adapted to the different conditions found at the new location and became the rest of the species Dendrosenecio. Dendrosenecio kilimanjari was the parent of them all.[3]
