this neighbourhood and sent to him by a Mr. Craig about 1880. Athyriinn 

 umhrosum. and Adpleniuni Hookerianum var. Colensoi were both collected by 

 Riches and are now recorded for the first time. 



In the accompanying list of existing species I give unrecorded habitats 

 for at least thirty ferns and lycopods. There is ample evidence that some 

 species now comparatively rare were once common — e.g., Leptolepia novae- 

 zelandiae and Polystichum adiantiforme. The former I have noted in 

 nine separate localities, and the latter in four, though no other recent 

 investigator has recorded them at all. Adiayitum ajffirie was once common 

 over the whole area and is still widely distributed, but is plentiful only 

 in a few localities, such as at Waterfall Gully on Mount Bossu, Nikau-palm 

 Gully, and the cliffs near Mat. Wight's Bay. Polystichum adiantiforme has 

 apparently not been recorded since Raoul first mentioned Akaroa as a 

 habitat, though Mr. Louis J. Vangioni has it growing in his fernery on 

 a fern-trunk from Grehan Valley, where I find it still fairly common. 

 Laing regards Raoul's record as '' probably an erroneous identification," 

 but this species still exists in all the main Akaroa valleys, and near 

 McDonald's, half-way up the Jubilee Road, at Wainui. , 



Referring to Dicksonia fibrosa, which he records from Wainui, Laing 

 says, " As I have no specimens, I am somewhat doubtful of the identifi- 

 cation." This fern is common in the Le Bon's Reserve, and has been 

 obtained near the head of Barry's Bay by Mr. E. F. Stead. Azolla rubra 

 is a new record on my own observation.
