Amongst the algae recently received at the Herbarium is an 

 interesting collection from the Chatham Islands forwarded by Miss 

 H. E. Maltby. These islands appear to possess a luxuriant marine 

 vegetation. Miss Maltby notes the profusion of weeds on the 

 shore ; and Mr. R. M. Laing, who for many years has worked at 

 the New Zealand marine flora, observes in a letter : " There are 

 many novelties to be obtained here ; in fact I have seen a good

The literature of the Chatham Islands algae is scanty. Agardh 

 published two short lists, and Reinbold includes the Islands in 

 his "Ergebnisse einer Reise nach dem Pacific. Meeresalgen." 

 Laing also has obtained some records. 



When the general character of the specimens received is 



marked 



hemisphere is at once apparent. As in the case of Phanerogams, 

 when one looks over any of the lists of algae from the Southern 

 hemisphere one cannot fail to be struck with the fact that if we 

 exclude a few cosmopolitan forms none of the species given occur 

 in Europe or N. America. New Zealand appears more strikingly 

 diverse in this respect even than Australia ; and it is to the flora of 

 this country that the Chatham Islands algal flora bears most 

 resemblance.
