''Dendrosenecio kilimanjari'' is a giant groundsel found atop Mount Kilimanjaro in Africa. 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''. Both genera are in the family ''Asteraceae''. The giant grounsels 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 - the 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. ==Infraspecific name synonymy== The names for the giant groundsels have become somewhat confusing: *''Dendrosenecio kilimanjari'' (Mildbr.) E.B.Knox subsp. ''cottonii'' (Hutch. & G.Taylor) E.B.Knox * *''Dendrosenecio johnstonii'' (Oliv.) B.Nord. subsp. ''cottonii'' (Hutch. & G.Taylor) B.Nord. * *''Senecio cottonii'' Hutch. & G.Taylor * *''Senecio johnstonii'' Oliv. subsp. ''cottonii'' (Hutch. & G.Taylor) Mabb. * *''Senecio johnstonii'' Oliv. var. ''cottonii'' (Hutch. & G.Taylor) C.Jeffrey *''Dendrosenecio kilimanjari'' (Mildbr.) E.B.Knox subsp. ''kilimanjari'' * *''Senecio johnstonii'' Oliv. var. ''kilimanjari'' (Mildbr.)
