Giant lobelia

In East African highlands as many as 20 species were listed in 1934 (Bruce).

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] While many of the East African species have a basal rosette, representatives in Hawai'i, for example, exhibit a diversity of forms.
