Cyanea duvalliorum Lammers & H.Oppenh.

Genus: Cyanea

Range: Maui; Haleakalā, windward wet slopes. USGS Map not available.

Growth form: Trees, 4-6m tall

This species discovered by Hank Oppenheimer, Fern Duvall, Renate Gassmann-Duvall and Marita Lewis in January 2000 on windward Haleakalā. It was discovered at the same time as Cyanea maritae which has similarly dissected leaves, but C. maritae is short and shrubby. In his paper, Lammers lays out his difficulty in placing these two new species, finally deciding that they belong with the Scabrae clade.
