Giant lobelia

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. Locations where given are from 1934 (Bruce) which also provides a key to these species.

The giant lobelia span Africa, Hawaii, South America, the Himalayas, and Southeast Asia. Phylogenetic analysis strongly supports that this is a monophyletic group. While many of the East African species have a basal rosette, representatives in Hawai'i, for example, exhibit a diversity of forms.
