Mr. Brown, on the Proteacee of Jussieu. 
nullo, pedicellis geminatis, raró pluribus fasciculisve unibractea- 
tis. Calyces sepissimé rubicundi, nunc flavi; in quibusdam 
obliqué inserti. Folliculi vel coriacei, ovati, stylo toto coronati ; 
seminibus ovalibus angustissimé marginatis et apice brevissime 
alatis : lignei, vel subrotundi, pseudo-bivalves basi tantum styli 
mucronati ; seminibus undique alatis. 
This extensive genus, of which a few of the least remarkable 
species have been already published as Embothriums by Dr. 
Smith, Cavanilles, and others, I have dedicated to the right 
honourable CHARLES Francis GREVILLE, one of theVice- 
Presidents of the Royal Society; a gentleman eminently 
distinguished for his acquirements in natural history, and to 
whom the botanists of this country are indebted for the in- 
troduction and successful cultivation. of many rare and in- 
teresting plants. | 
Grevillea is probably the most extensive genus of Proteacex 
in New Holland, and admits of division into several very 
. natural sections, most of which are readily distinguishable 
by more than one character, existing either in the parts of 
fructification or in habit ; notwithstanding which, I have not. 
ventured to separate them into distinct genera, as I probably 
should have done, had I been acquainted with fewer species ; 
but have given to each section a proper name, a practice 
| that may perhaps be advantageously adopted in all large 
genera, where they are thus capable of natural subdivision, 
It must be unnecessary to add that proper names can in 
‘this manner be given only where the sections are perfectly 
natural, and not in those cases where genera have been 
subdivided from single characters, and those too of but little 
importance, as in Thunberg’s division of Protea, from the 
form and division of the leaves ; to which may be opposed
