plants have been misidentified by inexperienced botanists, and thus Ilillebrand's 

 collection is not half as valuable as it was. Specimens of one species, coming 

 from different localities, have been separated and only one retained, instead of 

 keeping them together for comparison, a thing so necessary with Hawaiian plants 

 on account of their pol> morphism. We find what is to be regarded as the type 

 of Cyanca fevox, labeled Cijanea annata var. pinnatifida from Kamolo, Molokai. 

 The description of Vyatica fcros tits this specimen only; besides, there is no 

 specimen labeled Cijanca ferox in the Ilillebrand Herbarium. Prom his de- 

 scription of that species we learn that he had flowei'buds only and the specimen 

 here figured corroborates this fact. There is another sheet in the Hillebrand 

 Herbarium containing young leaves of Cyanca ferox and labeled as such. 



The writer collected this species at the heights of Waikolu, but it was neither 

 in flower nor in fruit. Mrs. L. ]\1. Dunbar collected this species recently with 

 flowerbuds : it evidently tlowcrs in the late sninmcr or autunni. 



There seems to lie some doubt as to the validity of the varieties of Cyanea 

 solaiiacca, and of the species Cyanea ferox and its variety from East Maui. Fur- 

 ther explorations will have to decide the question. The .straightening out of 

 Hillebrand's own material will serve as a good basis to build upon intelligentl.y. 

 The thinner leaves labeled Cyanea ferox ex coll. Hillebrand-Lydgate in the 

 Bishop Museum are probably referable to the var. fi. of tliat species from East 

 Maui. The leaves of the ]Molokai specimen are of thick texture.

 ovoid 7 lin. (14 mm) long, the linear-oblong lobes 14-18 mm; jjinnae or segments 

 of the leaves in young plants separated by small lobules or auricles."

The writer collected this variety in the type locality, on the western slopes 

 of Mt. Haleakala in the wet forest, on the crater of Puukakai, The following 

 is a description of the writer's material from Puukakai: 



A branching shrub 18-22 dm high, branching usually at the base, trunk and 

 branches covered with thorns; leaves all iiinnatiseet, crowded at the apex of the 

 branches; peduncles arranged all along the branches for about 25 cm, four to 

 five-flowered, bracteate at the apex, bracts 5 mm ; pedicels 10 mm, bracteolate at 

 the middle; flowers unknown; berry ovoid to oblong 20-25 mm, bright yellow, 

 crowned by the calycine lobes. 



It is very doubtful, however, if the JIaui plant is a variety of Cyanea ferox 

 from Molokai ; it would i-ather appear from the habit of the two plants that the 

 latter represents a distinct species {Cyanea horrida Rock), but as no mature 

 flowers are known of either at present, the varietal rank may be adhered to,
