30 ON THE PROTEACE/E OF JUSSIEU. 



and it is at least to be expected that in his own appli- 

 cation he is consistent with Plukenet, whom he means to 

 follow. 



44] To determine how far this is the case, I have examined 

 the figures published by Plukenet under the name of 

 Leucadendros, and also his Herbarium, which forms part of 

 the Sloanean collection in the British Museum. Of his 

 three species so named the first is Protect argentea, his 

 " Leucadendros africana arbor tota argentea sericea foliis 

 integris, Atlas Tree, D. Herman" of which the figure repre- 

 sents a branch without fructification, and a separate fruit 

 possibly of the same plant, but rather, as I suspect, belong- 

 ing to a different species of the same genus. 



On the same plate is figured a single leaf, in all pro- 

 bability belonging to P. conocarpa, with the following 

 name, " Leucadendro similis africana arbor argentea folio 

 summo crenaturis ftorida, an Leucadendros africana foliis 

 serratis D. Herman ?* The separate fruit accompanying 

 this, probably does not belong to it, but to some species of 

 that division of Leucadendron which Mr. Salisbury has 

 called Euryspermum. 



The third species, his " Leucadendros africana, sen 

 Scolymocephalus an gustiori folio cqncibus tridentatis" is a 

 good figure of a flowering branch of Protea cucullata. 



It could not certainly from his publications alone be 

 understood why the name Leucadendros is applied to these 

 three plants so little alike, while different names are given 

 to species much more nearly related to some of them than 

 they are to each other : of this however the solution is to 

 be found in his Herbarium ; on consulting which I find, 

 that after the publication of Protea argentea, with whose 

 flowers he was unacquainted, he had acquired flowering 

 specimens of Protea hirta, and had supposed these two 

 species to be the same, pasting between two leaves of 

 argentea four loose heads of hirta, and under the whole 

 copying in his own hand the name Leucadendros, &c. at 

 full length from his Phytographia, This satisfactorily 

 45] explains why he referred P. cucullata to Leucadendros, 

 its flowers being very similar to those of Protea hirta. As
