Prefatory Notice. 
ee 
Since the issue of Botany Bulletin XIV. in October, 1896, 
to the present date only three others have been issued, and 
these almost entirely devoted to special subjects: No. XV. 
records a large number of additions to our Freshwater Algee, 
No. XVI. mainly deals with the Fungi collected by Dr. Pritzel 
in Queensland in 1902, and No. XVII. with the additions to 
our ferns published by Dr. Domin in his ‘“ Prodromus einer 
Farnflora Queenslands.” Nearly all additions to our Flora 
since the inception of the Queensland Agricultural Journal in 
July, 1897, have been recorded in its pages ; it has, however, 
been considered that the “Contributions to the Flora of 
Queensland” were unsuitable for the Journal, and it has been 
decided to again issue Botany Bulletins as material becomes 
available. Records of fresh weeds which make their appearance 
and are likely to spread, and other matters of agricultural 
interest, will be-continued to be published in the Queensland 
Agricultural Journal.
