44 Mr. Bbown, on the Proieacece of Jussieu. 



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

 figures published b}' Plukenet under the name of Leucadendros, 

 and also his Herbarium, which forms part of the Sloanean col- 

 lection in the British Museum. Of his three species so named 

 the first is Protcn argentea, his " Leucadendros nfricana arbor 

 iota argentea sericea foUis integris, Atlas Tree, D. Herman." of 

 which the figure represents a branch without fructification, and 

 a separate fruit possibly of the same plant, but rather, as I 

 suspect, belonging to a different species of the same genus. 



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

 belonging to P. conocarpa, with the following name, " Leuca- 

 dendro shnilis africana arbor argentea folio summo crenaturis 

 forida, 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. 



Tlie third species, his " Leucadendros africana, sen Scohjmo- 

 cephalus angustiori folio apicibus tridentatis" is a good figure of a 

 flowering branch of Protea cucullata. 



It could not certainly from his publications alone be under- 

 stood 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 Her- 

 barium; on consulting which I find, that after the publication of 

 Protea argentea, Avith whose flowers he was unacquainted, he 

 had acquired flowering specimens of Protea hirta, and had sup- 

 posed 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 fidl length from 

 his Phytographia. This satisfactorily explains why he referred 



P. cucullata
