[The grasses of New Zealand have long been in need of care- 

 ful study and examination by some competent authority in 

 Europe, whose position would give him access to the large 

 European herbaria where the types of the published species 

 are mainly deposited, and where it is alone possible to work 

 out many questions relating to the geographical distribution of 

 the species, and their relationship to the grasses of the world. 

 No attempt to deal with the grasses of New Zealand with re- 

 gard to these points has been made since the publication of 

 Hooker's " Handbook of the New Zealand Flora " in 1864. 

 Buchanan's beautifully illustrated work, which has appeared 

 in the interim, though valuable in very many respects, is 

 wholly confined to the illustration and description of the 

 species, with notes on their economic value. During the forty 

 years that has elapsed since the preparation of the " Hand- 

 book " the classification has been to a great extent revolution- 

 ised. Different views are now held as to the position and 

 characters of many of the genera and species ; and an im- 

 mense amount of information has been obtained bearing on the 

 geographical distribution of the species. Among the workers 

 who have contributed to this advance no one is better known 

 than Professor Eduard Hackel, of St. Polten, Austria. To 

 say nothing of his monographs of the Andropogonecs and Euro- 

 pean Festucea, his account of the whole order published in
