Art. XLII. — On some Recent Changes in the Nomenclature 

 oj the Neiv Zealand Myrsinaceae.

[Read before the Philosophical Institute of Canterbury, 26th November, 



1902.] 



The ninth part of Engler's " Pflanzenreich,"* containing the 

 Myrsinacece by Dr. Carl Mez, Professor of Botany in the Uni- 

 versity of Halle, has recently appeared. The object of this, 

 paper is to publish for the benefit of such New Zealand bo- 

 tanical students as have not access to the above-mentioned 

 most important work an account of certain changes in nomen- 

 clature which affect the New Zealand species, since ''Das 

 Pflanzenreich" will, in all probability, be the authority on 

 plant-nomenclature for many years to come. 



The natural order Myrsinacece, according to Mez, contains 

 thirty-two genera, including 933 species, of which 348 are 

 described for the first time. Of these genera, two occur in 

 New Zealand— viz., Suttonia and Bapanea. Mez divides 

 Suttonia into two subgenera, Eusuttonia and Bapaneopsis. 

 Eusuttonia contains six species, if the species now known as 

 Myrsine coxii be added, which are all confined to the New
