Cyanea coriacea (A. Gray) Hillebr.

Genus: Cyanea

Range: Kaua'i, north, mesic valleys, 150-220 m.

Growth form: Treelet, 2.5-3 m tall.

Wimmer (1943) relegated Cy. fauriei, first described by Léveillé in 1911, as a variety of Cy. coriacea. In 2004, Lammers went further and sunk Cy. fauriei into Cy. coriacea. These plants were identical except for geography and inflorescence length. Cy. coriacea were those plants from northern Kaua'i with short, ascending racemes. Cy. fauriei were those plants from southern Kaua'i with long, pendant racemes. See discussion under Cyanea hardyi in Rock, 1917. Lammers found that raceme length is continuous and essentially clinal and therefore now considers these two to be the same species.
