ISLAND LIFE.

article was written. The most remarkable feature here is the 
great abundance of Lobeliacese, a character of the flora which is 
probably unique ; while the superiority of Labiatse to Legumi- 
nosse and the scarcity of Rosacese and Orchidacese are also very 
unusual. Composites, as in most temperate floras, stand at the 
head of the list, and as these have been carefully studied by Mr. 
Bentham, it will be interesting to note the affinities which they 
indicate. Omitting four genera and species which are cosmo- 
politan, and have no doubt entered with civilised man, there 
remain twelve genera and forty-four species of Composite in the 
islands. All the species are peculiar, as are six of the genera ; 
and in another genus, Coreopsis, the six species form a peculiar 
named section or subgenus, Campylotheca ; while the genus 
Lipochaeta with ten species is only known elsewhere in the 
Galapagos, where a single species occurs. We may therefore 
consider that eight out of the twelve genera of Hawaiian Com- 
posite are really confined to the Archipelago. The relations of 
the genera are thus given by Mr. Bentham : —

Distantly with Madiese and Galinsogesc of the

With Raillardella of the Mexican region. 
With Stifftia and Wunderlichia of the Brazilian 
region. 
The great preponderance of American relations of the Com- 
posite, as above indicated, is very interesting and suggestive. 
It is here that we meet with some of the most isolated and re- 
markable forms, implying great antiquity ; and when we consider 
the enormous extent and world-wide distribution of this order
