FERNS OF THE LAKE GreoRGE FLora—II 105 
autumn. When young, the rachis has a fine granular 
pubescence. In moist rich old woods, forms occur in 
which the lower pinnae are broadly unequally ovate.

Moist rich low woods; scarce. 
Bear pond, French Mt. (Hulst); Granville (Pember); 
southeast of Oneida near Halfway brook; north of Glen 
Lake; southern W. Fort Ann; west of Shushan about 
Clarks Pond and on Mt. Colfax; north of Cambridge. 
Variable. Specimens solidubed at Podunk Pond,

Dryorreris CLINTONIANA X INTERMEDIA Dowell 
Wilburs Basin, near Saratoga battlefield, Nov. 5,

1908. 
DRYOPTERIS CRISTATA X MARGINALIS Davenp. 
Swampy woods north of Cambridge (Dobbin & Burn- 
ham), Sept. 17, 1910. Determined by E. J. Winslow, 
Jan. 23, 1911, who says of D. Boottii, growing in the 
same woods. ‘‘Boottii has sori near the midvein and 
indusia glandular. The cristata x marginalis has sori 
more widely separated from the midvein, indusia 
smooth, and very acuminate tips of pinnae.”
