ANNIVERSARY ADDRESS. 23 



the works published by Oxl ey, King, Cunningham, Sturt, Mitchell, 

 Leichhardt, &c. It was not however, until 1878, that Mr. 

 Bentham, assisted by Baron Mueller, described in the seven 

 volumes of the Flora Australiensis all the known plants of 

 Australia, and thus collected together in one elaborate work after 

 sixteen years from (1863 to 1878) of unremitting exertion a full 

 account of our Flora as derived from all sources, whether from the 

 accumulated collections in Europe, or from those procured by 

 Baron Mueller in Australia. The Flora Australiensis, it should 

 be observed, describes the dicotyledonous and monocotyledonous 

 plants fully, but of the acotyledonous orders only the 

 Lycopodiacse, Marsilaceee and Filices, or what are termed the 

 higher Yascular Cryptogams. Between 1858 and 1881 

 Baron Mueller published eleven volumes of his Fragmenta 

 Phytographise Australia, containing descriptions in Latin of new 

 and rare plants, and also, in the last volume, lists of the lower 

 Cryptogams furnished from various sources. His Eucalyptographia, 

 his work on the Myoporinous plants of Australia, and that, now 

 in course of publication, on the genus Acacia, have contributed 

 materially to clear up difficulties in the classification of species, 

 and by means of well executed figures, to place before the student 

 in almost living reality some of the most interesting of Australian 

 plants. In his ' Systematic Census of Australian Plants,' to which 

 he has added several supplements, he has given a comprehensive 

 view of the Flora of Australia, showing the species peculiar to the 

 respective colonies, and raising the total number of vascular plants 

 to nearly 9,000. Whilst the progress of the past, especially 

 during the last quarter of a century, has been most satisfactory, 

 it is evident that the lower Cryptogams afford a wide field for 

 scientific investigation ; and it is to be hoped that specialists in 

 the various departments may be found to accomplish for the 

 Mosses, Lichens, and Fungi, what has been done so ably for the 

 higher orders of vegetation by Brown, Bentham, and Mueller. 

 Professor Harvey in his splendid ' Phycologia Australia?,' has 

 done much for the Marine Botany of these coasts, but as he
