for moisture upon the natural rain-fall. It is no dripping rock, such 

 as the ^ncojHfoif^ rarfica?ts usually flourishes upon. This may account 

 for the rather inferior size of the fronds from this locality. I brought 

 awa}' many specimens, and have succeeded in growing the fern in a pot, 

 under glass, in my house. 



I found in the same neighborhood Asplenium trichomanes, A. pinna- 

 tifidum, A. ebetieum, A. vxontanum, and A. riita-muravia ; Cainptosoms 

 rhyzophyllus ; Felice, airopurpurea, and many others. The Abies cana- 

 densis grows to a large size, with long, straight trunks, in the valleys, 

 and the Taxiis baccata var. canadensis is quite common. 



PoLYPODiUM ixcAXUM. — This fern is found growing on trees, on 

 Brush Creek, Adams county, Ohio, and also at Eock Springs, about 

 twelve miles from Louisville, Kentucky. I have never seen any men- 

 tion of it as being found on the lower Wabash, but, from the nature of 

 the flora of that river, I think it may be confidently looked for there. 



Asplenium montantjm. — Very fine specimens of this fern were 

 gathered by me near the entrance to Mammoth Cave, in Kentucky, in 

 August of last year. They were growing on limestone, and the fronds 

 measured from nine to ten inches in length. Many of the fronds are 

 bifurcated at some point between the middle of the frond and the apex, 

 or sometimes even lower down, giving the appearance of two fronds on 

 one stipe. 



Asplenium pinnatifidum. — I found in connection with the last a 

 variety of Asplenium pinnatijidum, which I deem worthy of mention. 

 These are some of the points in which it differs from the more usual 

 form : It is pinnate, the pinnse, as in many ferns, becoming more con- 

 fluent as they approach the apex. The apex, in my specimens, is less 

 prolonged, but is fertile throughout its entire length, as in ordinary 

 typical specimens. The divisions of the more usual fern touch, or, 

 more generally, overlap. The pinnse of my specimens are distant, the 

 interval between the lower pinnse being equal to the width of the 

 pinnse themselves. The lower pinnse obscurely lobed and denticulate. 

 The stipe is not so broad, and is brownish black at base, soruetimes 

 two thirds of the length. I did not see any other form in the vicinity 

 of Mammoth Cave, nor did I see the Comptosorus rhyzophyllus, though I 

 regard it quite probable it occurs there. If it deserves to be called a 

 variety, I suggest the name Asplenium pinnatifidmn var. pinnatum. 



BoTRYCHiUM LLTfARioiDES VAR. DissECTL'M. — For Several seasons I 

 have found, early in the spring, now and then, a stray plant of this 

 species. The sterile frond only remained, and it was thick and hardy 

 in aspect, and dull in color. These plants had evidently wintered 

 over, and may be regarded as hardy in 'this latitude. They are low, 

 and easily covered with leaves, *and readily escape observation. This
