Note 1 — Chapter XXII · THE ERA OF THE ENDEMIC GENERA (continued) The Compositæ and Lobeliaceæ (continued) The Age of the Tree-Lobelias

The materials are nearly all derived from the works of Hillebrand and Drake del Castillo. Some of those relating to the elevations in Hawaii are supplemented from my notes. All the genera are endemic except Lobelia, of which all the species are apparently endemic, excepting perhaps one, which, according to Hillebrand, resembles greatly a species from the Liukiu Islands.
