Cyanea Gayana is closely related to Cyanea fissa, from which species it dif- 

 fers iu the much shorter calyciue teeth, shorter, miilti-bracteate peduncles, and 

 peculiar habit of growth, being single stemmed, while Cyanea fissa is a much 

 branching shrub of often more than 4 m in height.

A distiuct species closely related to Cyaiua Gayana. Cyanea fissa and Cyanea 

 hirtella. 



It is very distinct from Heller's Cyanea sylvestris and has nothing in com- 

 mon witli C. anfiustifniia var. 8 as Hillebrand suggested.

 inent below, chartaeeous, 20-23 cm long (including a puberulous petiole of 15-18

KAUAI: Upper llanalei Valley, on ridge between Hanalei and Kalihiuui, 

 elevation 1800 feet, flowering October 17, 1914, G. K. Larrison no. 10342 type in 

 the herbarium of the College of Hawaii. 



A striking species somewhat related to Cyanea reeta. The corolla is only 

 slightly curved and almost black. It was named in honor of Jlr. (i. K. Larrison,
