ON THE PROTEACEiE OF JUSSIEU. 25 



but from the references to Boerhaave's figures it is evident 

 that the genus is to be understood in the same extensive 

 sense which he at length gave it in the second Mantissa. 

 In 1737 appeared the Genera Plantarum, and in it for 

 the first time the natural generic character of Protea : as in 

 this work he only cites Lepidocarpodendron and Hypophyl- 

 locarpodendron of Boerhaave, it follows that here the genus 

 is more limited, though its character is not peculiarly ap- 

 plicable to either of Boerhaave's genera referred to ; and 

 the description of antherse and germen is not reconcilable 

 to any plant whatever of the family. In the same year 

 Hortus Cliffortianus was published, in which he resumes 

 his first opinion of Protea, reducing to it all Boerhaave's 

 genera, but referring to the character given in his own 

 Genera Plantarum. It does not appear on what ground 

 this change of opinion was formed ; for in Clifford's garden, 

 according to Viridarium Cliffortianum, there had only 

 been two species, Protea urgentea and saligna, neither of 

 which had flowered, and the former was already lost ; while 

 in his Herbarium, now in the collection of Sir Joseph 

 Banks, the specimens of all the three species given in the 

 body of the work are without fructification, and of Protea 

 racemosa added in the appendix there is no specimen what- 

 ever. 



If Linnaeus is to be considered in a great degree the 

 author of the Prodromus Plorse Leydensis, published by 

 A. Van Royen in 1740, as has been asserted by some of 

 his pupils, and may be inferred from a passage in his 

 Diary published by Dr. Maton, it must be noticed as his 

 next work in the order of time ; for from the same Diary 

 it appears that he could only have been employed in its 

 composition in 1738. In this work the genus Protea is 

 given in the same extensive sense as in Hortus Cliftbr- 

 tianus, and no fewer than twenty-one species are charac- 

 terised, of which however only two were in the Leyden ps 

 garden, the rest being described from specimens in Van 

 i Royen's Herbarium. 



In 1738 he also published his Classes Plantarum, in 

 which, notwithstanding he appears to have composed it
