L-\ix<i. — Vegeiation of Banl-s Pt/u'ii-tvhi. 369 



V. Lavandiana could scarcely, if occurring, have been completely over- 

 looked by Cockayne, Wall, and nay self. I must therefore consider the 

 above three species as endemic on the peninsula till more definite evidence 

 is brought to the contrary. 



Cotula Haastii is another species which may be endemic on the 

 peninsula ; though recorded from the plains by Haast, it has not been 

 found there recently. There are other plants which are here represented 

 by varietal forms — e.g., Aciphylla .squarrosa, Angelica monfana, Anisotome 

 E)ii/sii, Mijosotis australis, Ourisia macrophi/lla, Veronica LijaUii, (fee. : but 

 as it is not my intention to deal with critical species in this paper I am 

 leaving these out of consideration here. Enough has been said to show 

 that there is sufficient endemism in the area to suggest its isolation for a 

 long time from any other portion of the country. 



Species at their Southernmost Limit. 



The following eighteen species probably here reach their southernmost 

 limit on the eastern coast. Some are to be found farther south on the 

 west coast. I give, where possible, some notes on their northward dis- 

 tribution. 



Alectryon excelsuni. — Abundant to the north of the Hurunui, and pro- 

 bably to be found in coastal valleys as far south as the mouth of the 

 Waipara (Double Corner). 



Angelica, rosaejolia. — If correctly reported by Raoul from Akaroa this 

 shows a remarkablv discontinuous distribution, as it is not otherwise known 

 outside the North Island. 



Clematis Colensoi. — Found also on the foothills to the west ; ocal on 

 the peninsula. 



Cordyline indivisa. — Does not occur on the coastal hills of North 

 Canterbury, and I have seen no record of it from the Kaikouras, where, 

 however, it may be expected to occur. 



Corynocarpus laevigata. — Common on the Kaikoura coast and as far 

 south as Gore Bay ; a single tree at Manuka Bay, north of the Hurunui ; 

 but does not, I think, occur between the mouth of the Hurunui and 

 Banks Peninsula. 



Cyathea CunningJiamii. — If the determination be correct this is a 

 remarkable southern extension of its range on the (^ast of the South 

 Island, but in Westland it extends beyond the Big Wanganui River. 



Dodoiiaea viscosa. — Common along the coast to the north of Pegasus 



^^y- .... 



Griselinia lucida. — I have not seen this south of Banks Peninsula, and 



doubt its occurrence, though reported in the Manual as not uncommon as 



far south as the Bluff. To the north of Banks Peninsula I have noted its 



occurrence at Manuka Bay, where typical specimens are to be seen on 



rocks, just to the north of the mouth of the Hurunui. It is not reported 



in the Dunedin Field Club's Catalogue (1916). 



Hedycarya arborea. — On the Kaikoura coast, but I have not seen it 

 between the Amuri Bluf¥ and Banks Peninsula. It is curious that on the 

 west coast it should occur as far south as Preservation Inlet, but it does 

 not pass beyond Banks Peninsula here. Possibly the arid Canterbury 

 Plains have proved a barrier to its southward progress. 



Leacopogon faaciculatum. — Occurs inland on Mount Grey dt)wns and in 

 the Lee Valley.
