2. A plea for a botanical survey. — At p. 63 of my 1897 

 address I gave reasons in support of this plea, but the 

 formal establishment of such a survey has not yet been 

 made. During the past fifteen years I have seen with much 

 pleasure, the steady increase in numbers of local botanists, 

 and I feel that we are getting measurably near to the 

 publication of serial " Records of the Botanical Survey of 

 New South Wales," in which no new record would be 

 accepted without quotation of a readily accessible and 

 authentic specimen. Such a serial would relieve the 

 already overburdened pages of our local scientific journals. 



As regards my suggestion (p. 69, loc. cit.) for the posting 

 of records in County and Parish Maps, I am as keen in 

 regard to it as ever, but no funds are available to pay a 

 man to do the work. I shall make a beginning, by publish- 

 ing, in my " Critical Revision of the Genus Eucalyptus" 

 coloured lines or "curving boundaries" on maps of Aus- 

 tralia to embody our present knowledge of the range of 

 each species. Publication of such maps (I am not referring 

 to any particular genus) will, I am satisfied, very actively 

 stimulate search in certain localities which appear to be 

 indicated. 



As regards a number of species, the full value of the 

 maps will only be brought out when they are accompanied 

 by indications of height above sea-level. Insets could also be 

 inserted in each map with particulars of specific localities, 

 e.g., swampy, limestone, etc. 



3. New Census of Neiv South Wales Plants. — The 

 endeavour of scientific classification of plants is to group 

 them naturally according to their affinities, and their 

 development from the lowest forms to the highest, but the 

 so-called Natural System used in the Flora Ausbraliensis 

 is natural only in the principal groups, and not even that; 

 the position of the Gymnospermae as a group of the Dicotyl-
