Mr. Brown, on the Proteacee of Jussieu. 39 
however only two were in the Leyden garden, the rest being 
described from specimens in Van Royen's Herbarium. 
In 1738 he also published his Classes Plantarum, in which, 
notwithstanding he appears to have composed it while engaged 
in the arrangement of Van Royen's collection, another fluctua- 
tion of opinion occurs, Protea being limited as in the first edi- 
tion of the Genera Plantarum, and to Leucadendros, which. 
here for the first time occurs, he refers the Conocarpodendron of 
Boerhaave. 
In 1740 he published th the second edition of Systema Nature, 
where the names Protea and Leucadendron are both given; but 
the references to Boerhaave are reversed, Protea being confined 
to his Conocarpodendron, and Leucadendron comprehending his 
other two genera. In this sense they also appear in the second 
edition of the Genera Plantarum published in 1742, in ‚which 
the character of Leucadendron is first given, some of whose 
species he must, from the annexed asterisk, have seen recent: 
his description of corolla. and pistillum is only 2. ei to. 
Lepidocarpodendron. | 
In 1745 Linnzus received the Herbarium of P from 
which he composed his Flora Zeylanica: the fourth volume of 
this collection containing a mixture of Ceylon and African 
plants, the latter are not noticed in this work; but from an in- 
spection of the Herbarium itself, now in the Banksian collection, 
it appears that he had added generic names to most of them :- 
of Protex only three species exist in the volume, of which Protea 
conocarpa is one: of this there are on the same page two speci- 
mens, whose heads of flowers are separately pasted ; under one 
of these specimens he has written Leucadendron, and under the 
second Protea; to a specimen of Protea Serraria on a different 
E. page
