found in Franklin County myself, but Miss Furbish 

 once collected it in Strong, and it ought to nourish in 

 the northern woods. Its variety flabelliforme Fernald 

 is the most common Lycopodium of all. Last but not 

 least is the very distinct L. trktachyum Pursh, its blue

Those botanists who have collected elsewhere in 

 northern New England will miss several species trom

 townships in Franklin County have been explored 

 botanically, it is not for me to say that such plants as 

 Pellaea atropurpurea do not grow within its limit- 

 there is any limestone area in the unexplored Km 

 it is mor. than possible that there are several other 

 species. Further than this, there are such quantities 

 of fern vegetation everywhere in woods, pastures, an
