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 fluctuation of opinion occurs, Protea being limited as in the first edition of the Genera Plantarum, and to Leucadendros, which here for the first time occurs, he refers the Conocarpodendron of Boerhaave.
In 1740 he published the second edition of Systema Naturæ, 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 applicable to Lepidocarpodendron.
In 1745 Linnæus received the Herbarium of Herman, 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 inspection of the Herbarium itself, now in the Banksian collection, it appears that he had added generic names to most of them: of Proteæ only three species exist in the volume, of which Protea conocarpa is one: of this there are on the same page to specimens, 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
