PRESIDENTIAL ADDRESS. 47 



Betche and myself. We have had the matter in hand for 

 some years, and are trying to present a useful publication. 



The last Census of plants of this State, was published by 

 my predecessor, Mr. Charles Moore, in the year 1884, and 

 consists of nothing more than a list of phanerogams and 

 vascular cryptogams taken from Mueller's Census, with 

 the volume and page of the Flora Australiensis added. 



In our Census the arrangement followed, as far as these 

 plants are concerned, is based upon Bngler's classification, 

 and is the first Australian Census following this order. 



The Pflanzenfamilien has not been slavishly followed, 

 but we feel that it is more scientific to begin with plants 

 of lower development and proceed to the higher, and, 

 having decided on that, it is well to accustom oneself to 

 the scheme. It is my intention to adopt the same arrange- 

 ment in the National Herbarium, but I feel that it would 

 be futile to do so before the issue of a revised Census. 



The Census contains references to the changes proposed 

 by modern monographers, references to good pictorial 

 illustrations, to useful botanical descriptions and notes, 

 and especially to information bearing on the inclusion of 

 the species in the New South Wales flora. 



The honorary specialists attached to the National Herb- 

 arium, viz.: the Rev. W. W. Watt for Mosses and Hepatics, 

 Mr. A. H. S. Lucas for Algae, the Rev. G. I. Piayfair for 

 Desmidaceee, will, in addition to Mr. E. Cheel for Fungi and 

 Lichens, supply tentative lists of the New South Wales 

 plants belonging to their various groups. It is our inten- 

 tion to publish additions to the Census from time to time, 

 on the same plan, so that it may be kept up to date.
