Hawaiian Lobeliads
“Unquestionably the crowning glory of our flora are the arborescent lobelias.” Vaughan MacCoughey -Botanical Gazette, 1917
A group of monophyletic plants within the Bellflower family (Campanulaceae) that are thought to have arrived in the Hawaiian chain roughly 13 million years ago. Many are orthophilous with a few exceptions. They are among the largest radiation of oceanic island plants derived from a single ancestor.
*I am currently (2022) updating the phylogeny following the great work of Lammers, Givnish, and Hunter. While no consensus yet, I’ll keep updating and revising as new information comes along.

Studia Mirabilium 
Hi Sebastian. What a great web site, and a wonderful array of information (and a lot of work). I led a Sierra Club group on Manoa Cliff on Sunday, and saw you briefly at the trailhead. I did not want to bother you guys and bring my group of 11 down to your site. Maybe I should have.
