ment of its contributors. To name them all would be 

 to list all the writers on ferns in America. We cannot 

 refrain, however, from a mention of Messrs. Saunders. 

 Maxon, A. A. Eaton, Graves, Bates, Dodge, Flett, Hill, 

 House, Waters, Dukes Ransier. Ferriss, Hans, and Miss 

 Slosson. To these, and to all the others who have helped 

 our magazine to success, the sincere thanks of the editor 

 are extended. 



The study of the ferns and fern allies must continue 

 to change with changing conditions. New species are 

 no longer among the probabilities, though forms and va- 

 rieties may still be found for many years to come. In 

 the recording of these, with such additional facts about 

 old species as may come to light, is work sufficient to 

 keep the magazine busy for many years. That it may 

 continue to engage in this work is the earnest hope of 

 its editor. 



Habitat of Polypodium Scouleri. — In the Fern Bul- 

 letin 9:40-42, 1901, Air. S. B. Parish has a paper entitled 

 " Southern Extension of the Range of Polypodium 

 Scouleri." I chanced upon it recently, and note that in 

 speaking of this species, he says : " Although this some- 

 times grows in the soil, its usual situation is the mossy 

 trunks of trees." I have collected it on the San Bruno 

 hills, San Francisco, and near the shore beyond Pacific 

 Grove, Monterey County, and at both places it was 

 growing on large granite boulders in crevices where a 

 foothold could be obtained. Both of the localities cited 

 are exposed to the cool ocean winds as well as to con- 

 siderable fog, and are outside the line of arborescent 

 growth. — A. A. Heller in Muhlenbergia.
