Mailing Small Ferns. — Mr. H. E. Ransier suggests 

 that a most convenient way to mail small ferns is by the 

 use of the " Photo-mailer " envelopes, which may usually 

 be obtained of the nearest stationer or photographer. 

 They are strong and light and protect ferns as well as 

 they do photographs. 



Polypodium Vulgare Auritum. — Dr. Fellows in his 

 list of Maine Ferns (Fern Bulletin, October, 1906) 

 states that Polypodium vulgare auritum has been found 

 only in one station in the State. This fall I have found 

 it in quite abundance and from specimens I have 

 from other stations I should judge that my find was 

 a very fine one. — Henry W. Merill, Hiram, Maine. 

 [We are indebted to Mr. Merrill for some excellent 

 specimens of this but most of the fronds more properly 

 belong to P. Vulgare hastatum, which has ears on both 

 sides of the pinnae. Some, however, are eared only 

 on the upper side. As there seems to be no name for 

 this particular form Mr. Merrill's name may well stand 

 for it. The form has been illustrated in The American 

 Botanist for September, 1903. — Ed.] 



The Eared Walking Fern. — It is not every day that 

 one finds the walking fern (Camptosorus rhizopkyllus) 

 with the base of the frond prolonged into sharp-pointed 

 "ears." It seems to occur only in the thriftiest plants, 

 and is undoubtedly due to unusual vigor. It will be 

 found upon examination of any leaf that veins and lobes 

 bear a close relationship to each other. When the walk- 

 ing fern puts out these ears they will be found to be coin- 

 cident with the formation of larger basal veins. The 

 ears behave quite like the tip of the frond and may oc- 

 casionally root and produce new plants, just as the tip 

 of the frond does. Mr. H. C. Bigelow writes that he 

 found an eared frond recently near New Britain, Conn., 

 that was eighteen inches long. He has found several, 

 always where the soil is moist and the colony shaded. The
