==== Hawaiian lobelioids ====
Hawaii is also the site of a separate major floral adaptive radiation event: the [[Hawaiian lobelioids]]. The Hawaiian lobelioids are significantly more speciose than the silverswords, perhaps because they have been present in Hawaii for so much longer: they descended from a single common ancestor who arrived in the archipelago up to 15 million years ago.<ref name="Baldwin" /> Today the Hawaiian lobelioids form a clade of over 125 species, including succulents, trees, shrubs, epiphytes, etc.<ref>{{Cite journal|last1=Givnish|first1=Thomas J|last2=Millam|first2=Kendra C|last3=Mast|first3=Austin R|last4=Paterson|first4=Thomas B|last5=Theim|first5=Terra J|last6=Hipp|first6=Andrew L|last7=Henss|first7=Jillian M|last8=Smith|first8=James F|last9=Wood|first9=Kenneth R|last10=Sytsma|first10=Kenneth J|date=2008-10-14|title=Origin, adaptive radiation and diversification of the Hawaiian lobeliads (Asterales: Campanulaceae)|journal=Proceedings of the Royal Society B: Biological Sciences|volume=276|issue=1656|pages=407–416|doi=10.1098/rspb.2008.1204|pmid=18854299|issn=0962-8452|pmc=2664350}}</ref> Many species have been lost to extinction and many of the surviving species endangered.
