The artificial pond, ‘‘Mud Lake,” is one used for 
irrigation purposes so the level is not constant. The 
plants when collected were growing under several 
inches of water—a few of the plants having their tips 
near the surface. An attempt to get more of this plant 
will be made the coming summer. 
The Polystichums listed from Noyo River and Mt. 
Shasta, have been presenting a good many questions to 
me, and to gain assistance in answering these questions 
I have sent the entire lot to Mr. Hopkins. He says, 
“the material is certainly very interesting and I have 
been looking at it with longing eyes for some time.”

I find it interesting, in connection with Mr. Knowl- 
ton’s list,! to recall some collecting experiences of ten 
years ago in Auburn. Me. Auburn is in Androscoggin 
County, which touches Franklin on the south. Being 
nearer the coast it lacks several northern and mountain 
species such as Polystichum Braunii, Aspidium Goldi- 
anum, and Lycopodium sabinaefolium. Perhaps the 
fact that I did not find Woodwardia virginica and 
Lycopodium inundatum is accounted for by the rather 
narrow range of my explorations. I had one good 
station for Phegopteris hexagonoptera, one for Asplenium 
platyneuron, one or two for Selaginella rupestris, and 
several for Asplenium Trichomanes and W oodsia ilvensis. 
One plant of frequent occurrence. in Auburn surely 
will some day be added to the Franklin County list. 
That is Botrychium simplex. It was found in pastures 
and sterile fields, usually associated with B. ramosum. 
Sixty miles west of Franklin County, in Vermont is 
a region much like the Farmington country where
