28 OX THE PROTEACEiE OF JUSSIEU.
ever, he had in his Herbarium : the first, Leucadendron speciosum, he had probably accidentally seen, the antherae of which are described as filaments, and their callous apices alone as true antherae : the description of the second, L. pini/olium, is by Van Royen.
In the twelfth edition of Systema Naturae published in the same year, the species of Leucadendron are arranged in a different, and, as the author intended, a more natural order ; from which it may be concluded that at this time considerable additions had been made to his Herbarium : but L. glomerabum is unaccountably omitted. Protea here receives again P. Levisanus, the P. fusca of the first edition of the Species Plantarum, which in the second had been referred to Brunia.
In Mantissa altera published in 1771, the two genera are united under the name of Protea \ new characters are 42] given to the species, and most of them are described from specimens then in his Herbarium ; five species are added which had already been published by the accurate Bergius ; and three, P. totta, strobilina and parviflora, are here first met with : in his description of the last he seems to suspect it to be a male plant, which we now certainly know to be the case. P. glomerata is here again taken up ; but Protea acaulis, can cell at a and conocarpa are omitted ; and Protea conifera of the second edition of the Species Plantarum is subdivided into three species, P. conifera, p aliens and saligna.
In the thirteenth edition of the Systema Vegetabilium published in 1774, the essential character of the genus is adapted to its present state, and no alteration occurs among the species, except that P. speciosa is considered as a variety of P. Zepidocarjjodendron.
From this statement it appears, that Linnaeus in his earlier works had not sufficient materials for obtaining an accurate notion of this family ; and hence that perpetual fluctuation of opinion concerning it, which has been now pointed out, and may in few words be recapitulated.
1st, He gave the genus Protea the same extent which he at length assigned to it in the Mantissa.
