Cockayne, following Bentham and Hooker, has in all his recent papers 

 referred the New Zealand species of Ligusticmn to Aciphylla. But, as 

 Cheesenian points out (1909, p. -108), this latter genus is best limited to 

 the Aciphi/llae proper, a most distinct group, and if it be thought correct 

 to limit Ligusticum to the northern species, then Hooker's genus Anisotome 

 might well be revived for the reception of the southern species. This 

 course we have taken, since we consider Anisotome a true antarctic genus, 

 notwithstanding, as in the cases of Nothofagus, Nothopanax, and Celmisia, 

 it has a strong northern affinity. 



(5.) Nertera species. 



The species of Nertera in the list, which occurs also on bogs in the Wai- 

 makariri Valley, differs from N. depressa in its orange-coloured pyriform 

 drupe, that of the latter being globose and red ; but we have no material, 

 and are writing from memory, so are unable to give a name and description 

 to the plant. Probably it has hitherto been mistaken for N. depressa, since 

 the drupes oii being dried would lose their distinctive shape. 



(6.) Olearia arborescens (Forst. f.) comb, no v. — Solidago arborescens 

 Forst. f. in Prodromus, p. 298, 1786. 



This is the well-known 0. nitida Hook. f. in Handbk. of N.Z. Flora, 

 p. 125, and it is a great pity the name has to be changed in accordance 

 with the rules of botanical nomenclature. 



(7.) Celmisia spectabilis Hook. f. 



A very distinct form was common on Prospect Hill. This is dis- 

 tinguished from the type by the leaves being not " entire or minutely 

 serrulate " (Cheeseman, 1906, p. 308), but coarsely and distantly toothed 

 almost to the base. Young leaves on a cultivated example exhibit the same 

 toothing.
