This is oni' of the handsomest species of Cyanea : it is of palm-lik'c liabit and 

 reaches a height of 2-4 feet (8 m). Unfortunatel\- it is exceedingly scarce and the 

 writer fears that it has become extinct. AVhere there was once a forest at 

 Ulupalakua there is now onl\' grass land with planted Eucalypti. Tlie writer 

 met with liut a single plant in a very narrow ravine which was inaccessi1)l<' to 

 cattle. 



Horace Alauii's description of the inflorescence is wrong; the peduncles are 

 long and many-flowered and not " pediiiicnlis axiUaribus brevibus pauci/loris." 



The trunk is simple erect or (as in the case of tlie writer's specimen 1 l)rancli- 

 ing near the base. 



In the Gray Herbarium is a drawing of a Ciiinua from Alakawao, Maui, 

 marked />r/i'.s.scfl arhorca! in Asa (Jray's handwriting. It was drawn from a 

 specimen collected by F. L. Clarke in 1877, and bears the following legend: 

 "From 20-40 feet in height. Leaf entire-sessile; veins anastomozing, coriaceous, 

 slightly downy on the upper surface; veins distinct." The specimen itself is 

 missing; only a section of the stem is ])reserved in an envelope. 



The plant, as can be judged from the drjiwiiiii-. is not closely related to 

 C. arhorca, still less identical with it. It w(]uld eonie closer to Ci/aiirti (H/'fiirdil, 

 which has the flowers arranged in a similar way at the apex of the iieduncle. It 

 is probablj' intermediate between ('. sujxrha and C. Giffanlii. Ilillebrand's 

 var. /3 of Cyanea arborea from the woods of Ililo, is not to be found in Ilille- 

 brand's Herbarium; judging from the short tlescriptiou it is probalily itlentical 

 with the writer's ('. (li/f'airlii, but liesides the arborescent stature it is very dif- 

 ferent from ('. firhiiriii and could not be chissed as a variety of the latter.

Leaves smaller, mcinliranous, runuing out into a distinct petiole of 3,75 cm, 

 pubescent underneath; pediinele slendci' naked, 7.5-10 cm long, bearing at its end 

 a cluster of sessile subglobose. truncate lieri'ics 12 mm in dianietei-, the acute tri- 

 angular calyx-lobes 4 mm. 



HAWAII: Koliala ranue, Ilillebrand. 



This variety has never been re-collected, nor is there a specimen lo be found 

 in Ilillebrand's collection in the Berlin llerliarium.
