profusion at Ararat Summit in northeastern Pennsylvania. The 

 locality was a damp, deciduous wood, at an altitude of about 

 2,100 feet, and if a special convention of Fern Allies should ever 

 be called for that place, the local reception committee would be a 

 respectable one. Besides the two species just named, there 

 were there, B. Virginianum, B. ternatum (just appearing, the 

 special form not then distinguishable), Lycopodium clavatum, 

 L. lucidnlum, L. obscurum, L. annotinum, and L. complunatum ; 

 while in the immediate neighborhood, within calling distance, so 

 to speak, were Egnisetum sylvaticuni, E. arvense, and E.flicvia- 

 tile, to say nothing of /socles echi'nospora Braunii abundant in 

 ponds three or four miles away. 



The floor of ihe wood referred to was deep with the undis- 

 turbed leaf mould of many years, and was everywhere humped 

 in short, low ridges or hummocks. It was in the damp, rich de- 

 pressions between these hummocks that B. lanceolatum and 



B. matricari&folium were invariably found. Diligent search on 

 the part of myself and of Mr. Clute, with whose company I was 

 favored upon the occasion of a visit to the wood a few days later, 

 failed to reveal a single plant of either growing upon the hum- 

 mocks, except an "Occasional one near the base. Both species 

 were very sociable, plants of each often growing side by side and 

 sometimes sharing the same bit of old brown leaf to push up 

 through. 



In size, B. lanceolatum was found varying from about two 

 inches to six and a half, the sterile leaf very regular in its tri- 

 angularity, and the fertile portion usually profusely branched. 



C. matricariafolium, which was the more abundant species 

 there, grew from four inches to ten or eleven in height, the larger 

 plants as fleshy as aldermen. It was noticeable that the sterile 

 leaves of this latter species were quite variable in form — some 

 being lanceolate in outline with roundish divisions barely 

 toothed, while others were ovate in outline with long, slender 

 deeply cut divisions; some were forked at the apex. The fertile 

 spikes of this species were noted as usually almost simple, or at 

 most very sparingly branched, and their sporangia at the time 

 of our visit had burst open and become brown. The sporangia 

 of B. lanceolatu7n, on the other hand, were still green and un- 

 opened. 



The low stature of these Botrychiums and the small expanse 

 of surface of the one leaf that each plant bears, make them
