Sources:[1][2] Dendrosenecio kilimanjari is a giant groundsel found on Mount Kilimanjaro in Africa, below 4,000 metres (13,000 ft).

It was originally known as Senecio kilimanjari, but a recent botanical reclassification split off some species formerly in Senecio, putting it and various other species in the new genus Dendrosenecio.

The giant groundsels of the genus Dendrosenecio evolved, about a million years ago, from a Senecio that established itself on Mount Kilimanjaro, with those that survived adapting into Dendrosenecio kilimanjari.

This later colonised other mountains by some means - a standard distance for wind dispersal of seeds is a few metres - and these isolated populations adapted in ways different from the parent population, creating new species.
