  • Phylogenetic comments: 2022 updateCyanea hardyi is part of the coriacea clade of Cyanea with mostly a Kaua’i radiation. This clade of possible hybrid origin between the pyrularia  clade and angustifolia clade has a fairly large diversification of species on Kaua’i.
  • My notes: Limahuli Gardens is such a jewel on the north coast of Kaua’i; I really have to do a proper post on it one of these days. They have a nice representation of Hawaiian lobeliads, with Cyanea hardyi being one of the more prominent ones.
