Thelypteris-like fronds; and from both of which it is soon 
known by one of those indefinable graces of appearance that 
Sometimes gives character and tone to a plant just as a cer-

young crosiers just beginning to unfold while those of A. 
Thelypteris and A. Noveboracense were from six to eight in- 
ches high, and in the Quincy swamp matured plants were 
fresh and green when A. Noveboracense in the neighboring 
woodlands had become brown and yellow. : 
Unlike A. Thelypteris, too, this fern is at its best in ne
