Art. XXVIII. — Notes on the Indigenous Vegetation oj the North-eastern 

 Portion oj the Hokonui Hills, with a List of Species. 



By D. L. POPPELWELL. 



[Bead before the Otago Institute, 14th October, 1919 ; received by Editor, 24th October, 

 1919 ; issiied separately, 23rd June, 1920.] 



The Hokonui Hills consist of the high country which lies within the 

 triangle formed by the Gore-Invercargill section of the Main Trunk Rail- 

 v/ay, the Invercargill-Lumsden section of the Invercargill-Kingston line, 

 and the Waimea Railway. They are roughly triangular in form, Gore, 

 Lumsden, and Winton being the corners. Each side of the triangle is about 

 thirty miles long, the total area being therefore about 300,000 acres. The 

 highest point (Bare Hill) is 2,260 ft. above sea-level. The most southerly 

 point is not more than a few miles from the sea, whilst the northern end 

 extends about thirty miles inland. The Hokonui Hills are isolated from 

 the surrounding chains, being bounded by the valley of the Oreti on one 

 side, the Mataura valley on another, and the Southland Seaward Plains on 

 the third side. It is palpable that the different parts of a stretch of country 

 such as this must show considerable difference in their plant covering, as 

 they extend from near the sea to quite beyond what is usually accepted 

 as the littoral belt. This block contains several thousaM acres of bush, 

 but most of it consists of uplands divided by several more or less open 

 valleys with constant streams. Every class of soil and situation is there- 

 fore presented, and consequently the plant-life is of a very varied kind. 

 To attempt to give a complete report would be a task quite beyond the 

 time at my disposal at present, hence I will confine my remarks to that 

 poTtion of the Hokonuis nearest Gore, locally known as Croydon Bush, 

 and the uplands in the vicinity. I have also to point out that these notes 

 do not profess to be exhaustive. Numerous introduced plants are also 

 found, but are not further mentioned. The highest point in the area dealt 

 with is East Peak (2,000 ft.) and an unnamed peak to the westward thereof, 

 which is slightly higher than the former.
