Ninety-two species, besides several plants universally cultivated 
in the Pacific, are common to Vavau and the Sandwich Islands. 
Vavau possesses none of the Cyrtandreew which are cha- 
racteristic of the mountains of Fiji; no Melastomacee except 
Memecylon Harvey?, no Saxifragacew, no Vacciniacee, and the 
orders Rubiacew and Orchidacesw are poorly represented. Herein 
its flora differs strikingly from that of Fiji, where the greater 
elevation, greater age (greater permanence), and wider range of 
soil and climate favour a richer flora.
