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.
