Killawog, in Broome county. It is there plentiful. Fruit 

 nearly as in Pteris. This cliff is composed of shales, with per- 

 haps a very slight amount of lime in them. The slender cliff - 

 brake is one of the few species that is supposed to be confined 

 exclusively to limestone rocks, and its occurrence here is remark- 

 able. 



WOODWARDIA J. E. Smith. 



W. Virginica ( L. ) J. E. Smith. Virginian Chain-Fern. Rare. 

 Brisbin peat-bogs, Coville. Thompson's Marsh, Clute. Beebe's 

 swamp and swamp at Oakland, Graves. Bog north of Barton, 

 Fenno. The only stations. Fronds in appearance very much 

 like Osmunda Cinnamomea, except that they are borne singly 

 and not in clumps and the fruit dots occur on the backs of 

 fronds that resemble the sterile ones. In localities where one 

 does not expect it, this is probably one of the easiest of species 

 to overlook. Good botanists frequently pass through it think- 

 it an Osmunda. 



ASPLENIUM L. 



A. Trichomanes L. Maidenhair Spleenwort. Wall Spleen- 

 wort. Dwarf Spleenwort. Fairly common on the rocky walls 

 of nearly all of our deep ravines. Fronds seldom more than six 

 inches long, pinnate, several from a common centre, forming 

 green rosettes. Fruit dots linear, on the backs of the pinnas. 

 This species is a lover of the deepest shade, but thrives well 

 under cultivation in a rockery. 



A. platyneuron (L. ) Oakes. Ebony Spleenwort. Common. 

 Found only in rocky uplands in partial or complete shade. Stipe 

 very short, it and the rachis black and polished. Fronds some- 

 what larger than the preceding, the sterile, half reclining; the 

 fertile, later, erect and longer than the sterile ones. While 

 never found growing on cliffs in our region, it still seems to 

 need the touch of the rock. Given a hillside covered with loose 

 shale, and this fern may be expected. {A. ebeneum Ait.) 



A. angustifolium Michx. Narrow- Leaved Spleenwort. In rich 

 woods. Brown. Van Etten, N. Y., Barbour. The only stations. 

 Fronds tall, thin, once pinnate, the fertile ones produced but 

 sparingly.
