A number of genera, at least quite as large as that of the pre^ 

 ceding series, are not referable to any hitherto described, and will 

 prove, I trust, a valuable contribution towards the botanical 

 system, inasmuch as the discovery of new generic types assists 

 in disclosing the laws of affinity in nature, connecting often those 

 forms which are isolated by wide chasms, and aiding thus in the 

 advancement and accomplishment of a truly natural system of the 

 whole existing vegetation. • 



j^l The amount of plants added by our travels to the Australian 



flora approaches to 800 species. A few of them are incidentally 



Mentioned in the works previously quoted, none 1 

 duced by systematical descriptions. How many 



and

jtions, and by access to a more extensiv€ 

 at my command. Still I am imder th 

 500 of the additional plants are peculiar 



and these must 



new to botany.
