Cyanea calycina (Cham.) Lammers

Genus: Cyanea sect. Rollandiae

Range: O'ahu, Wai'anae Range, scarce in Ko'olau Range; mesic and wet forest, 300-915 m.

Growth form: Treelet, 1-3 m tall.

This species was only raised from subspecies level in 1998 (Lammers, 1998).

How to identify: Very similar to Cyanea lanceolata, differentiated on the branched or clustered trichomes on the leaf undersurface. Other differences between Cy. lanceolata and Cy. calycina are 1) Cy. calycina has a longer hypanthium, 2) the calyx lobes are oblong with obtuse, rounded or truncate apices versus triangular calyces with acute or obtuse apices in Cy. lanceolata and 3) only Cy. calycina is found in the Wai'anae range. Both species are found in the Ko'olau range, but Cy. calycina is rare there.
