There are no specimens of either the species or the supposed variety in the 

 Gray Herbarium. The plant is only known to the writer from Ilillebrand's 

 and Mann's specimens. 



The writer collected in September, 1910, a Cijaiica above Jlakawao, East 

 ilaui (no. 8517), which may be referrable to Cijanca obtusa. Ilillebrand re- 

 marks about the stem of this species as having a compact wood with narrow 

 cavity; the writer's material has the stem hollow, but divided into narrow 

 chambers by horizontal chartaceous diaphragms.

This species is characterized by the thick leathery leaves, long petioles and 

 short, stout racemes. It was confused by Hillebrand and other writers with a 

 different species from Olokele canyon, which was recently described by H. Le- 

 veille as Cijanca Faurici. 



Cyanea coriacea has only lieen re-collected once since Jules Remy's time, by 

 v. W. Hardy in the Waioli river liasin on Kauai at an elevation of between 

 500 and 700 feet, and not 5000-7000 feet as misprinted in the Torrey Bot. Club
