MOLOKAI: Valley liack of Kaluaaha, Rock, observed only. 



A very eonmion species at the lower levels back of Honolulu and the main 

 ransc. The plants found in the valleys back of Honolulu are all alike, forming 

 shrulis with few erect branches, while those of the Koolau range beyond Kahana 

 Valley are small trees or much branching shrubs, with denser crown and nuich 

 broader leaves Hillebrand classes with this species plants found on West and 

 East !i\laui, which dift'er decidedly from those of Oahu ; ('i/aiica angustifolia is 

 very varia1>le and ranges into Cgdiua Hardgi, ('. Faurici and Cyanea, coriacca; 

 these three species are, however, very nnich larger plants.
