1222 president's address. 



Dining the last yeai' Baron von Mueller has made several 

 additions to his valuable "Census of Australian Plants," a work 

 which affords the means of tracing the geographical limits of 

 species, and estimating their numbers in the Australian Colonies 

 respectively. He has just published the Tenth Decade of his 

 Eucahj2:)togra2)hia, thereby completing a handsome volume con- 

 taining descriptions of figures of one hundred species of the genus 

 Eucalyptus, a genus which, since the days of R. Brown, has been 

 a sou'-ce of intense difficulty to botanists. Though some thirty or 

 forty species remain to be described, they are for the most part of 

 a shrubby nature, and not of the same economic value as those 

 mentioned in the present volume. This work is one of the 

 greatest in which the Baron has been engaged, and must ever 

 remain as an enduring monument of his ability and perseverance. 



In addition to several new plants described by him in Melbourne 

 periodicals during the year, he has issued a supplement to the 

 Fragmenta Phytograjjlme Australim containing a list of Australian 

 Fungi enumerated by the eminent mycologist Mr. C. Cooke. His 

 latest efforts have been dii'ected towards geographical discovery in 

 Australia, he having been elected Vice-President of the Victorian 

 branch of the Geographical Society recently formed. 



Mr. C. Moore, F.L.S., Director of the Botanical Garden, has 

 published, "A Census of the Plants of New South Wales," 

 compiled from Baron von Mueller's list and arranged according to 

 the system of the Flora Australiensis. 



Mr. R. D. Fitzgerald, F.L.S., has issued another part of his 

 elegant work on Australian Orchids, in which he has figured and 

 described sevei'al new species. 



Mr. F. M. Bailley, F.L.S., of Brisbane has made some important 

 additions to his Syno2Jsis of the Queensland Flora, in describing 

 new species and furnishing some interesting accounts of Crypto- 

 gamous Plants. 



Mr. J. E. Brown, F.L.S., has in course of publication, under the 

 auspices of the South Australian Government, an elegant work on
