Grevillea is the largest genus of Australian Proteacex, 
and the second largest of Phenogams in that continent, 
where it is surpassed in numbers by Acacia alone. which 
contains 313. ‘There are 156 species of Grevillea in 
Bentham’s “ Flora Australiensis” (1870), and in Mueller’s 
last “‘ Census of Australian Plants” (1889) there are 161. 
The only extra Australian members known are a few from 
New Caledonia, and one from New Guinea. As with so 
many large genera, it is difficult of subdivision into well 
defined groups, though the species are in the whole remark- 
ably constant, and their synonymy is more due to 
misnomers and duplication of names than to the erecting 
_ of varieties into species. In this respect, as well as in the 
limitation of the species by brief diagnoses, Grevillea com- 
pares favourably with Eucalyptus, as is evidenced by a 
comparison of the spaces required for the diagnoses of the 
species of those genera respectively in Bentham’s Flora. In 
that work Grevillea, with 156 species, occupies only eight 
pages, whilst Eucalyptus with only 124 species occupies 
ten and a half. 
G. Hilliana is the twentieth species figured in this
