Xaiithoj-uhim dipcfalum Kauaiciisc, Elacocarpus bifidiis, and others of the drier 

 regions. Cyanca recta inhabits the interior of the ishmd with C Caijana and 

 C. rivnlans, but is rather rare. 



While Kauai is rich in species Oahu is comparatively poor, but this is com- 

 pensated by the number of species of Rollandia of which genus only a single 

 species is found outside of Oahu. 



Cyanea angustifolia is by far the most common species occurring on the lower 

 slopes of the mountains all over the island. C. acuminata with white tiowers is 

 subherbaceous but still five to six feet in height and inhabits the denser rain- 

 forest. Intermediate between the two stations we find Cyanea Grimesiaiia. The 

 palm-like type of Cyaneas with loose-leaved crowns as we find in the rainforests 

 of both west and east Maui and Hawaii are absent on Oahu, but their place is 

 taken by Cyanea superba and C. regina both stately plants and resembling 

 greatly Cyanea Giffarclii of Hawaii and C. arborea of Maui. 



Cyanea truncata is found on the lower mountain spurs in dense jungle; it 

 seems to be confined to the Koolau range from Waiahole to Punaluu valleys. 



ifolokai has produced the smaller palm-like species which have open loose- 

 leaved crowns resembling those of Cyanca aculcatiflora on ;\Iaui and Cyanea 

 tritoinantha on Hawaii Their representatives on the island of ilolokai are 

 Cyanea solcnocaly.r, C. Wailauensis, C. solanacca and C. feror, as well as 

 C. procera. they all inhabit the dense rainforests, and may be found on the 

 ridges on the leeward siiles as well as in the deep ravines of Wailau and I'elcknnu 

 on the windward sides. In the drier leeward gulches we find ('. anguslifolia, 

 while C. prnfuga is found in the valley of Mapulehu at a comparatively low ele- 

 vation. Lanai possesses only one species C. Gibsonii. of Cyanca atra-tyyit^ while 

 two varieties of Cyanea angnslifolia (var. laiialcnsis and var. raci mosa), occur 

 in the gulches as !Mahana and Kaiholeua. 



The island of Maui, owing to its topographical diversity, altitude, and rain- 

 rail has produced a goodly number of very interesting species. The most note- 

 worthy being Cyanca aeuleatiflora and C. Jiamatiflora two very distinct species 

 inhabiting the dense rainforests of the northern and north-western slopes of Mt. 

 Ilaleakala at an elevation of from five thousand to six thousand feet. The 

 former species extends into the deep ravines of Waikamoi and Pnohaolcamoa 

 (see Plate XXXIV), where it grows fifteen to twenty feet in height or even more. 

 in company with masses of Gunnera petaloidea, Labordea, Pelea, etc. Cyanca 

 liamatijiora extends from Olinda to Waikamoi but is especially partial to Punka- 

 kai an ancient densely wooded volcanic cone in the rain belt above Makajvao. 

 Cyanea atra is found both on West and East Maui. In the former locality it is 

 not uncommon in the upper portion of Ilonokawai gulch and in the latter is 

 fdiuul along the Ukulele pipe line trail, a thousand feet higher tiiaii Cyanca 

 ac^ileatiflora. C. asplenifotia. C. linlophylla and lobata are found on West Maui 

 in the gulches of Wailuku and back of Kaanapali in deep ravines. The latter 

 ?pecies occurs also along the Nahiku-Keanae trail. One of the finest and 

 niost interesting species however is Cyanca arborea. I'nfortunately the 

 [)lant is practically extinct. It occurred on the slopes of Ilaleakala between 

 Kula and I'lupalakua. Anyone familiar with the forest region, or rather region, 

 as the forest has gone, can see wliy C. arhorca one of the finest of hidtdinidj ne 

 of the Hawaiian I.slands had to succuml). Where there was onci' fine forest
