Bicknell : Ferns and flowering plants of Nantucket 53 



Not seen in the western quarter beyond Trot's Swamp. Much 

 less common than the following. 



Anchtstea virginica (L.) Presl. 



Common, especially on the eastern side of the island, wherein 



many places it forms a luxuriant growth in bog holes and wet 



thickets; extends into Saul's Hills. Not seen west of Trot's 

 Swamp. 



Asplenium Filix-foemina (L.) Bernh. 



Uncommon ; Rattlesnake Bank ; Watt's Run ; Saul's Hills, one 

 station ; Trot's Swamp. The specimens met with were mostly of 

 moderate size and represent no extreme form of this fern, being 

 quite representative rather of the general species as commonly 

 understood. Professor Underwood, to whom specimens were 

 submitted, concurred in this view. Some examples, however, 

 approach var. angustum (Willd.) Moore. As a rule the fronds are 



ong-lanceolate or narrower, twice pinnate or nearly so ; pinnae 

 close-set to rather widely separated, lanceolate, spreading or 

 ascending ; pinnules crowded or well separated, linear to oblong, 

 broadly rounded or slightly narrowed to the apex, serrate or 

 incised, at least basally, with dentate segments ; indusium short, 



e curved. The specimens from Saul's Hills are small and of 

 very delicate texture. On Sept. 5, 1904, their fertile fronds were 

 completely withered, whereas the more typical plant in Trot's 

 Swamp was in perfect condition. Variety Mciiauxii Mett. (= var. 

 Migustian Moore) and " var. rhacticum Moore " are both mentioned
