ON THE PROTEACEJL OF JUSSIEU. 31 



to his application of this name to P. conocarpa, it could 

 only proceed from his total ignorance of its fructification ; 

 for, as he has figured a nearly related species, P. hypophylla, 

 under the very different name of TItymelea, &c., it is 

 reasonable to conclude, that had he seen the flower of 

 P. conocarpa he would have given it the same generic 

 name. This P. conocarpa however, of which it may truly 

 be said he knew nothing, and concerning which at least no 

 information is to be derived from his works, is the only 

 species of the three which belongs to Mr. Salisbury's genus 

 Leucadendron. 



But the original Leucadendros of Hermann, of Plukenet, 

 and of Linnaeus himself, is Protea argentea, the only plant 

 of the family to which the name can properly be applied ; 

 to this therefore I have assigned it in the following arrange- 

 ment. 



Before proceeding to this arrangement, I am happy in 

 having an opportunity of acknowledging that assistance 

 which has so liberally been afforded me. 



To the invaluable Herbarium and Library of Sir Joseph 

 Banks I have on this, as on all other occasions, enjoyed the 

 freest access ; an advantage which has been greatly en- 

 hanced by the opportunity it has given me of consulting 

 my friend Mr. Dryander, both as to the formation of genera 

 and respecting synonyms, on which points his sound 

 judgment and unrivalled erudition so well enable him to 

 decide. 



To Dr. Smith I am indebted for the permission of in- 

 specting the Linnean Collection, and for the most friendly 

 and satisfactory answers to the queries on this subject 

 which he allowed me to put to him. 



Mr. Lambert, whose Herbarium in this tribe is only 

 surpassed by that of Sir Joseph Banks, has, with his [46 

 accustomed liberality, submitted it without reserve to my 

 examination. 



Mr. Hibbert, who for many years possessed the most 

 extensive collection of living Proteas that has ever been 

 formed, and who also received from his intelligent collector 

 Mr. Niven a valuable Herbarium of native specimens, most
