LYCOPODIUM POROPHILUM IN THE DELLS

A week's sojourn in the Dells of the Wisconsin in 

 August, 1910, gave me an opportunity to study in

 (Aug. 19th) closely corresponds with mine (Aug. 11- 

 18) I must have seen them in about the same stage of 

 development as did Underwood. The type was taken 

 in October; the other collections were all made in 

 June. 



Soon after meeting with it the first time it became 

 a question to me whether it was specifically distinct. 

 Having a copy of the "Manual" with me it was readily 

 identified with the variety. It was first seen on shelves 

 of rocks in a deep ravine called the Artist's Glen ; the

 SB^- lucidulum was also found in the latter ravine, and
