THE FERN BULLETIN 7 



Lycopodmm complanatum. Scarce on a dry bank 

 near Chamcook Lake. 



Lycopodium complanatum flabelliforme. Common. 



Isoetes echinospora braunii. Frequent along the 

 south margin of Chamcook Lake and abundant in a 

 small shallow stream which flows from Chamcook 

 Lake to the seas. In this stream this species and 

 Lo photo car pus spongioses were practically the only 

 macroscopic vegetation and the Isoetes formed 

 dense mats and existed here over some hun- 

 dreds of square yards.

ANOTHER FORM OF DICKSONIA. 



BY WILLARD N. CLUTE. 



As our country grows older and the chance of find- 

 ing new ferns diminishes it is practically certain that 

 more attention will be given to the forms of ferns than 

 they receive at present. It is scarcely likely that our 

 students will ever take up this side of the 

 subject with the enthusiasm with which it is 

 handled in Great Britain — our climate does not 

 favor it, for one thing — but when the study of 

 forms does come in for more intensive treatment the 

 forms known at present will be all the better for be- 

 ing named and I take this opportunity to add still 

 another to the described forms of Dicksonia. 



Had the plant which produced this form been pre- 

 served and multiplied it would have been considered 

 quite the handsomest member of qur fern flora. The 

 two secondary pinnae which we illustrate natural size 

 can give but a poor idea of the beauty of the whole 

 frond. Its appearance strongly suggests some of the 

 tropical Davallias. The form differs from the type in
