PREFACE. V. 



the above mentioned standard work, a list of the recent alterations 

 is appended. 



The specimens of the New Zealand Grasses described in this work 

 are all preserved in the Colonial Herbarium, in Wellington ; and the 

 sources from which they have been received are duly acknowledged in 

 every instance when they have not been collected by Mr. Buchanan 

 himself. As some few grasses have been discovered very recently, and 

 by different collectors, it has been difficult to avoid the duplication of 

 specific names in cases where they have been independently described 

 by different authors, but the cases in which such duplication has been 

 ascertained are recorded in the list of addenda.
