﻿A new Hawaiian Cyanea 



The genus Cyanea belongs to the family Campanulaceae, 

 subfamily Lobelioideae, and is endemic to the Hawaiian Islands. 

 It contains more species than any other Hawaiian genus of this 

 subfamily, most of the species being arborescent. On the island 

 of Kauai the species are few in number but decidedly distinct. 

 On the islands of Maui and Molokai they are more numerous 

 but also more variable, certain of the species apparently merging 

 into one another. The species described below is named for 

 Mr. G. K. Larrison, superintendent of hydrography.
