II. Nephr odium spinulosum. 



A day was taken to visit Conneaut Lake, a small 

 but pretty sheet of water near the village of Edinboro, 

 Erie County. Ferns were abundant here, but mostly 

 of kinds common in suitable localities of the contigu- 

 ous regions where trips were made. Only a couple 

 need be mentioned. One of these was Nephr odium 

 spinulosum growing in the moist woods of hemlock 

 and yellow birch common around the lake. It was the 

 specific form, one I do not often meet with. It might 

 have been overlooked in the abundant representation 

 of the variety intermedium had not its much darker 

 colored sperangia called attention to it. It had the 

 glandless indusium which is given as one of the dis- 

 tinctive characteristics of the specific form. Whether 

 this very dark, almost black color of the sporangium 

 is a common or only a local peculiarity I am not pre- 

 pared to say, as experience with the form is limited. 

 But it is quite in contrast with the brown color that 

 characterizes the sporangia of such speciments as I 

 have and with all recollections of it. 



III. Dicksonia punctilobula. 



The other fern to be mentioned as occurring near 

 Edinboro is Dicksonia punctilobula. It interested me 

 for two reasons, because I had rarely seen it and be- 

 cause of its peculiar distribution westward as far as 

 the evidence points. A small tuft of the fern was 

 found in a scantily wooded pasture. It was on a clayey 

 knoll under a little hemlock tree, whose lower branches 

 mingled with the tops of the fronds. The find was a 

 welcome one since I had met with it but twice before 

 in 1861 in Maine, and earlier in the August of 1909 

 in Genesse County, N Y., thus after so long an in- 

 terval getting it twice the same month. Here it was
