Huge rocks and masses of coarse debris abound, and generally 

 there are mountain tarns and waterholes. Here the subalpine 

 becomes mixed with some of the alpine vegetation ; the 

 plants grow in profusion and with great luxuriance, forming 

 when in bloom, from the end of November till the end of 

 January or middle of February, beautiful natural flower- 

 gardens. 



Appendix. 



The following notes on the effect of the severe winter 

 of 1899 on plants, more especially on native trees and 

 shrubs at Hororata, were most kindly furnished by Sir John 

 Hall :— 



(1.) List of New Zealand Trees and Shrubs damaged by the 

 Frosts of June and July, 1899. 



Olearia forsteri in nearly every instance was completely 

 killed ; it has suffered perhaps more than any other native 

 tree, even when completely sheltered. Height in some in- 

 stances, 7 ft. 



0. traversii very badly damaged ; in most cases killed out- 

 right ; in other cases the lower parts were unhurt. 



Veronica salicifolia (plant 5 ft. high) completely killed. 



Pittosporum eugenioides and P. tenuifolium in most cases 

 were considerably damaged, especially towards the tops. A 

 hedge of P. tenuifolium which had been kept closely clipped 

 suffered very severely, every leaf being browned, but it may 

 possibly recover. 



Drimys axillaris suffered badly in some cases. 



Panax arboreum has suffered very badly, and most likely 

 in many cases has been killed outright. 



Clianthus puniceus killed outright. 



Griselinia littoralis for most part undamaged, but many 

 leaves have dropped off, apparently through the effect of the 

 frost. 



Podocarpus totara slightly browned in places, but virtually 

 quite unhurt. 



Senecio greyii considerably damaged.

not damaged.
