57. SMOOTH WOODSIA 



Woodsia glabella 



Northern New York and Vermont, and northward from Labra^

 stalks jointed at base. 



Fronds. Very delicate, linear or narrowly lanceolate, smooth 

 on both sides, pinnate ; pinna roundish ovate, obtuse, lobed, lobes 

 few ; fruit-dots scattered ; indusium minute.

 it is still more delicate ; its fronds are almost per- 

 fectly smooth, its outline is narrower, and its pinnae 

 are but slightly lobed. 



Mr. Pringle tells us that a letter from Mr. George

 account of these early fern hunts is inspiring in its 

 enthusiasm : 



" In 1873 George Davenport was beginning his 

 study of ferns. A letter from him, asking me to look 

 for Woodsia glabella . . . started me on a fern hunt. 

 The species had been found on Willoughby Moun- 

 tain, Vt, and at Little Falls, N. Y.; might it not 

 be growing in many places in Vermont? When I 

 set out I knew, as I must suppose, not a single fern, 

 and it was near the close of the summer. You can 

 imagine what delights awaited me in the autumn 

 woodlands. I made the acquaintance of not a few 

 ferns, though it was too late to prepare good speci- 

 mens of them. In this first blind endeavor I got, of
