The writer has not collected this variety and nothing is known of its habit. 

 It is very close to Cyanea obtusa and together with that species, Cyanea Mannii 

 and the other varieties of Cyanea angustifolia may form one very variable 

 species, which might all be included with Cyanea angustifolia. One would then 

 have to include Cyanea Paiirici, Cyanea Harelyi, C. coriacea and also C. spatli- 

 ulata. all fi-oni Kauai.

 (flowerbuds), Ilillebrand in Herbarium Berlin, herbarium College of Hawaii, 

 and Gray Herbarium. 



The writer has not collected this species ; it is only known to him from the 

 Hillebrand material. 



The species is undoubtcdl.v very closel.v related to Cyania angustifolia and 

 may be only a variety of it. It differs from it in the pubescent inflorescence 

 and the longer calycine lobes; the leaves are like those of C. angustifolia.
