From the list of species the curious fact will be noticed that Nothofagus 

 is completely absent from the area dealt with, and, so far as my observations 

 go, from the whole Hokonuis. This is difficult to account for, especially 

 as this genus is common on all the surrounding hill-groups. 



In time to come, when the botanical districts of New Zealand are 

 divided into subdistricts, the absence of Nothofagus alone will almost justify 

 th'e setting-apart of the Hokonuis as a subdistrict of the South Otago 

 Botanical District. 



In the meantime I do not propose to describe the plant formations, 

 but merely append a list of species observed during many visits to the 

 north-eastern portion of the Hokonuis. The list contains 285 species 

 comprising 146 genera, and spread over 57 families.
