Giant lobelia is a common name for several plants in the genus Lobelia; many of these species are restricted to high altitude, alpine ecosystems. In East African highlands as many as 20 species were listed in 1934 (Bruce). A selection of species names is below.

Giant lobelia and Senecio plants in Mt Kenya.

The giant lobelia span Africa, Hawaii, South America, the Himalayas, and Southeast Asia. Phylogenetic analysis strongly supports that this is a monophyletic group. [3], [4]
