ON THE PROTEACE/E OF JUSSIETJ. 41 



marck in P. pini folia, was first ascertained in Auhix and 

 the present genus (as Mr. Dryander informs me) by our 

 countryman Masson, during his last residence at the Cape 

 of Good Hope, and is beautifully illustrated by that 

 eminent botanical painter Mr. Francis Bauer, in his un- 

 published drawings preserved in the Banksian collection. 

 Numerous observations on the same subject have also more 

 recently been made by Dr. Roxburgh and Mr. Niven, who 

 have bestowed much pains in ascertaining its limits, of 

 which, as far as regards the African part of the family, 

 Mr. Salisbury has given an accurate account in his Essay 

 already quoted. The Dissertation of Thunberg, who was 

 wholly, unacquainted with this separation of sexes in these 

 plants, is necessarily imperfect, and he has, in several cases, 

 described the different sexes as distinct species ; and thus 

 also Bergius has founded his genus Aulax on the male of a 

 species, whose female he had previously published as a 

 Leucadendron. On the other hand, Jussieu, deceived by 

 the resemblance in inflorescence, between Brabejmn and the 

 spiked species of Protea, has erroneously suspected these 

 to be monoicous, while he has totally overlooked the truly 

 dioicous nature of the present genus.
