Ohs. In my general observations on Proteacese I have 

 noticed two very remarkable characters of Synaphea, 

 namely, the cohesion of the barren filament with the 

 stigma, which is peculiar to this genus, and the structure 

 and connection of the antherse, in which it agrees with 

 Conospermum : it is also remarkable that these two nearly 

 related genera should diifer in the position of their barren 

 and fertile stamina with relation to the perianthium ; 

 plants of the same natural family very generally agreeing 

 in the order of abortion or suppression of these organs ; 

 to thisj however, some other exceptions are known, and one 

 has been already noticed as occurring in Drapetes. 



The genus Synaphea seems to be confined to the south- 

 west coast of New Holland, for it is more likely that 

 Polypodium spinulosum of Burmannus {Jlor. ind. 233. t. 

 67./. 1.) which I have formerly referred to this genus, as 

 well as Adiantum truncatum of the same author, long since 

 determined to be a species of Acacia, by Mr. Dryander, 

 were brought from that coast to Batavia by one of the 

 Dutch navigators, perhaps by Vlaming, than that they are 

 really natives of Java, from which Burmannus received 

 them.
