ever, he had in his Herbarium : the first, Leucadendron 

 speciosum, he had probably accidentally seen, the aiitherae 

 of which are described as filaments, and their callous apices 

 alone as true antherse : the description of the second, L. 

 pinifolium, 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. glomeratmn is unaccountably omitted. Protea here 

 receives again P. Levisatius, the P. fusca of the first edition 

 of the Species Plantarum, which in the second had been 

 referred to Erunia. 



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, strohilina 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, cancellata and conocarpa are 

 omitted ; and Protea conifera of the second edition of the 

 Species Plantarum is subdivided into three species, P. 

 conifera, pallens 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. Lepidocarpodendron. 



Prom this statement it appears, that Linnseus 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.
