foundation has been laid for the canying on of the study of 

 various important gi'oups, and among the most interesting of the 

 subjects to which the Baron devoted his attention ave those of 

 genera and orders possessing in Austraha peculiar characters and 

 forming often a special feature of the flora. I refer in jiarticular 

 to his Monograph entitled " Eucalyptographia," consisting of 

 descriptions, with plates, of 100 species of the genus Eucalyptus, 

 and to the series of illustrations of Acacia, consisting of 13 

 decades or 130 species, Salsolacete of 9 decades or 90 sjiecies, and 

 of Candolleacese 1 decade only. A Avork on the MyojDorinefe con- 

 taining figures of a large number of the species of Myoporuni and 

 Eremophila was also begun and one volume completed. When it 

 i5 considered that there are probably at least 150 species of 

 Uucalyptus' and that only 100 are given in the "Eucalyptographia," 

 and that out of more than 300 species of the genus Acacia only 

 130 are figured, it will be seen that a large amount of work 

 remains to be done with those groups alone. 



The Baron's note on Boronia Jl jribunda, read at the meeting 

 of this Society on September 30th last, is belieAed to be his last 

 scientific contribution. 



A fitting memorial to the late Baron would be the publication 

 of a supplemental volume to the "Flora Australiensis." 

 As he took so important a part in furnishing material for the 

 seven existing volumes, it would be a graceful tribute to his 

 memory to dedicate the supplement to him. This work should 

 of course be carried out on the lines and according to the same 

 system as that adopted in the " Flora," which, whatever its 

 objections may be, has very much to recommend it, not only on 

 account of its being that made use of in the "Genera Plantarum," 

 but chiefly because a supplement could only thus be of real 

 utility. It would, however, be a convenience if at the end of the 

 volume a reference in taljular form to the system and nomen- 

 clature of the Baron's Census were supplied. It is to be hoped 

 that in whatever way the work may be carried out, all jealousies 

 will be laid aside and the greatness of the man to whose memory 

 the tribute is offered alone remembered. This volume might well
