PREFATORY AND OTHER NOTES. 



The present publication is a second edition of the " Catalogue of 

 the Indigenous and Naturalised Plants of Queensland," which was 

 published in June, 1890. 



The system followed is, for the Phanerogams and higher 

 vascular Cryptogams, Bentham and Hooker's Genera Plantarum 

 and the Flora Australiensis ; for the other Cryptogamic Orders, 

 various authors of high reputation. 



As one may easily suppose, a vast number of the State's 

 plants have been brought to our knowledge since then. These will 

 be found recorded, and in most instances with descriptions, in my 

 various publications of later years in the " Queensland Agricul- 

 tural Journal." This has been of great advantage to all persons 

 wishing to keep up a knowledge of the State's Flora, for, within a 

 few weeks of a plant's discovery, a description of it has been given 

 in the pages of that journal. However, this Catalogue, in which 

 may be consulted all the known plants to a given date, will always 

 he of very great value, not only to Queenslanders but to botanists 

 generally. 



With the idea of extending its usefulness, great changes have 

 been made, both in the arrangement and contents of the work. 

 The figures have been given at the special desire of Dr. the Hon. 

 Win. Kidston, who considered they would be helpful to persons 

 possessing but a slight knowledge of botany. 



In all plants marked as containing " Prussic Acid," a Hydro- 

 cyanic (Prussic) Acid yielding glucoside had been found by Mr. 

 J. C. Brunnich, F.C.S., Queensland Agricultural Chemist, or other 

 chemists. Where a plant is marked " Poisonous " it must be 

 understood that it has been suspected of being poisonous to stock ; 

 but in many cases this has not been satisfactorily proved.
