A remarkable little, almost shrubby Composite, a native of 

 Hawaii, in the Sandwich Islands, whence our valued correspon- 

 dent Dr. Hillebrand sent it to Kew in 1858. The species in- 

 habits the lofty volcanic mountains of that island, at elevations 

 of 10,000 feet, where it was originally detected by Mr. Macrae, 

 a collector for the Horticultural Society of London. 



The genus Mailliardia is an example of the singular fact, that 

 many genera of arborescent and shrubby Composites are peculiar 

 to remote oceanic volcanic islands, and are often represented to 

 a great extent in different islets of these groups by different 

 species, no species of such genera being found in other parts of 

 the world. Thus in the Sandwich Islands alone we have Bail- 

 Uardia with nine species, and Bubautia with four ; in the Gal- 

 lapagos, Scaleria with six ; in Juan Fernandez there is Bobin- 

 sonia with four species ; in Tahiti Fitchia ; whilst in the isle of 



June 1st, 1865.
