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
