This paper records the habitats of certain plants growing in the Eastern 

 Botanical District of the South Island as defined by Cockayne (1). Only 

 such plants are included in the list as have not previously been recorded 

 from this district or are of rare occurrence ; or such as have been omitted 

 from published lists of the florulae of defined areas ; or such, again, as 

 add to our knowledge of their distribution. 



No catalogue has been prepared of the species occurring in the above 

 district other than that of J. B. Armstrong (2). and, as it is by no means 

 certain that all of his identifications were correct, there is room for a 

 revision of the flora. Again, Armstrong's habitats are so vague as to be 

 of little service to students of this district. Most of the plants named in 

 this paper have already been recorded from Canterbury, though the specific 

 habitats given are new. 



Twelve native plants are added to the sixty-eight already recorded by 

 Dr. Cockayne as occurring in the Riccarton Bush, Christchurch (3 and 4). 

 Hymenophyllum minimum is recorded from this botanical district for the 

 first time. Helichrysum Purdiei has previously been collected in Canterbury 

 by Dr. Cockayne, Professor Wall, and Mr. H. H. Allan. Eryngium vesi- 

 culosum and Deyeuxia Billardieri are new records for Banks Peninsula. The 

 habitat mentioned for Carex Berggreni is the most northerly for this species, 

 while the genus Gahnia seems to have eluded the notice of observers since 

 Armstrong recorded five species in his catalogue (2). The recorded habitat 

 for Gleichenia Cunninghamii is worthy of note.
