Beown. — On the Genus Grimmia. 409 



Dicksonia lanata. 



This interesting fern is mentioned in the Handbook as 

 growing in Massacre Bay, but it has not been reported as 

 collected since Mr. Travers found it. Mr. Bryant drew my 

 attention to it near Coal Creek, Pakawau, and he tells me he 

 found it near the coal-mines on the "West Coast some years 



ago. 



In addition to the foregoing, there were many others more 

 or less rare or interesting : Pimelea avenaria in abundance 

 on the sandhills; Mentha cunning Jiamii, with its powerful 

 mint-like odour ; a good number of species of Coprosma, 

 including grandifolia and baueriana. Of ferns we found 

 Lomaria banks ii, Lomaria nigra, and the beautiful Lomaria 

 fraseri in fair abundance ; Tricliomanes elongatum, colensoi, 

 and strictum abundant ; Asplenium umbrosum, the finest 

 specimens I have yet seen, we found near Ferntown, the 

 pinnae at the base of the frond extending to a width of 2ft. or 

 more. Lycopodium laterale and Scliizcea fistulosa were also 

 plentiful. I hope to be fortunate enough to make another 

 visit at some future time, since the fauna and geology, as well 

 as scenery, are most interesting.
