On the Ferns in the Vicinity of Mont reed. 491 



Dicksonia pilosiuscida is only recorded by Maclagan, and 

 is found behind the cemeteries. 



There are only three species which I have been so far 

 unable to discover, but which may possibly still occur. 

 These are Aspidium Goldianum, Camptosorus rhizophyllus 

 and Botryckium ternatum. 



Aspidium GoleUeinnm, Hooker, is of especial interest, as 

 Montreal is the locality where it was first discovered, in 

 1818, by Mr. Goldie, after whom it was named by Sir 

 William Hooker. Since then it has been recorded by 

 Maclagan, McCord and Goode, though Mr. Goode writes, 

 in 1879, that he has not found it for some years. I have 

 been unable to discover it in the locality described by 

 these writers. 



Camptosorus rhizophyllus, Link, is represented in the 

 Holmes Herbarium by a specimen from St. Helen's 

 Island. It is recorded from l'Abord-a-Plouffe and St. 

 Helen's Island by McCord, and from Montreal Mountain 

 by Provancher. It probably does not now occur on the 

 mountain or on St, Helen's Island. 



Botrychium ternatum, Swz., var. luneirioieles, has also 

 been recorded by McCord and Goode, and a specimen, 

 marked " Montreal, 1861," is in the McGill Herbarium, 

 but I have not succeeded in finding the fern in this vicinity. 



In the following list I have chiefly given the distribution 

 of the various species on the mountain, as that is the 

 locality to which I have devoted most attention. The 

 mountain consists of three separate hills, divided by Cote 

 des Xeiges road and the cemeteries. For convenience of 

 description I have referred to these as Mount Eoyal and 

 the North and West Mountains. 



Polypodium culgeire, Linn. — Polypody — Rather common, 

 especially abundant on the north-east slope of Mount 

 Eoyal, growing on loose rocks. 



Adiantum pedatum, Linn. — Maidenhair. — Common in 

 many places, in rich woods and on wooded hillsides.
