(8.) The North-eastern South Island* Botanical District.— -This includes 

 all the north-eastern portion of the South Island except the Marlborough 

 Sounds Subdistrict. It is bounded on the south by a line, as shown on 

 the map, extending from the mouth of the Hurunui Eiver to the average 

 limit of the western rainfall east of the Hope Saddle, and thence on the 

 west by the average eastern limit of the western rainfall to some point or 

 other on Tasman Bay, probably near Motueka. 



(9.) The North-western South Island Botanical District. — This is bounded 

 on the east by the western boundary of the North-eastern District, and 

 thence by a line following the average eastern limit of the western rain- 

 fall to near the Hurunui Pass. Its southern boundary extends from midway 

 between Greymouth and Hokitika, thence to a few miles north-east of 

 Lake Brunner, and thence to a little to the east of the Hurunui Pass. 



(10.) The Eastern South Island Botanical District. — This is bounded on 

 the north by the North-eastern District, on the south by a line following 

 the Rivers Waitaki and Ohau to Omarama, and thence extending to a 

 point, shown on the map, lying to the westward of Lake Ohau near the 

 dividing range at the average eastern limit of the western rainfall. On the 

 west the boundary is the average eastern limit of the western rainfall. 



(11.) The Western South Island Botanical District. — This is bounded on 

 the north by the southern boundary of the North-western District, on the 

 east by a line following the average limit of the western rainfall, and on 

 the south by a line not yet determined, but extending possibly from a few 

 miles south of Jackson Head to a point, shown on the map, on the eastern 

 limit of the average western rainfall, a little to the south of the Haast Pass.f 



(12.) The North Otago Botanical District. — This is bounded on the north 

 by the Eastern District, on the west by a short line marking the average 

 eastern limit of the western rainfall, extending from the south-western 

 corner of the Eastern District to a point ; shown on the map, marking 

 the average eastern limit of the western rainfall, a few miles to the south 

 of Lake Wanaka. Its southern boundary, as shown on the map, is most 

 irregular in shape, and extends from about Waikouaiti, along a line 

 denoting the average northern limit of the south-western rainfall, and 

 terminating at the point south of Lake Wanaka already mentioned. 



(13.) The South Otago Botanical District. — The northern boundary of 

 this district is the southern boundary of the preceding district ; its western 

 boundary the average eastern limit of the western rainfall as shown on the 

 map ; and its eastern and southern boundaries the sea. 



(14.) The Fiord Botanical District. — This is bounded on the north by 

 the southern boundary of the Western District, on the east by the western 

 boundaries of the North and South Otago Districts, and on the west and 

 south by the sea. 



(15.) The Stewart Botanical District. — This includes Stewart Island and 

 all the adjacent islets, including those of Foveaux Strait. J The Snares 

 Islands are related floristically and ecologically to this district, but the 

 evidence is in favour of their being constituted a special district of the 

 Subantarctic Botanical Province.§ 



* For sake of brevity in using the above term the words " South Island " are usually 

 omitted, and so with certain other South Island districts.
