l68 Mr. Brown, on the Proteacea of Jussieu. 



tiullo, pedicelUs geminatis, raro ph/ribiis fasciculisve tinibracteci- 

 tis. Calyces seepissimi rubicundi, tiuiic jiavi ; in quibusdam 

 oblique inserti. Folliculi vel coriacei, ovati, stylo toto coronati ; 

 seminibus ovalibus angustissime marginatis et apice brevissime 

 alatis : lignei, vel subrotimdi, pseudo-bivalves bast tantum styli 

 mucronati ; seminibus undique alatis. 



This extensive genus, of which a few of the least remarkable 

 species have been already published asEmbothriums by Dr. 

 Smith, Cavanilles, and others, I have dedicated to the right 

 honourable Charles Francis Greville, one of theVice- 

 Presidcnts 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 Proteaceae 

 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 1 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
