Tlie specimen in the Paris Hei'barium, collected by Gaudichatid, is labeled 

 Delissea acuiiiiiKita var. There is no question of its identity, though only a 

 few leaf fragments and a portion of a peduncle are left. On the label is 

 written: "fleurs blancli anthcres violaees. cal. overt flavescent, fruits jaune- 

 orange arondis lobez overtc flavescent * * * (a part is not legible) plant 

 sont laetescentes, etc. ' ' 



This species is very distinct, and ([uite common in the mountains back of 

 Honolulu ; it is conspicuous in the forest on account of its mass of white flowers 

 clu.stering along the stem in the axils of fallen leaves for often more than 18 cm. 

 In the writer's opinion Cyanea acuminata is much closer affiliated with Cyanea 

 Bislwpii, and the many varieties of Cyanea pilosa, than with Cyanea angustifolia. 

 It has the habit of the first mentioned species, being somewhat subherbaeeous and 

 only woody at the base, while Cyanea angustifolia is a muchbi-anehed robust 

 shrub, or even small tree. It is therefore inchided in the section with Cyanea 

 pilosa. Wawra records a variety latifolia from Mt. Kaala, Oahu, no. 2251 ; it i.s, 

 however, doubtful if that plant has anything in common with this species, he 

 having collected leaves only.

Dr. Gray suggests tliat this species is doulitless related to (^'hamisso's Lobelia
