188 BOTRYCHIUM 



MATRICARY GRAPE FERN: 



Botrychium ramdsum. 

 (B. matricariae folium; B. neglectum.) 



The matricary grape fern is quite similar in 

 form to the lance-leaved and intergrading forms 

 are frequent. It is the more common of the two. 

 The sterile division is egg-shaped or triangular in 

 outline^ joined to the main stalk by a short stem, 

 varying from pinnate to twice pinnatifid, the lobes 

 rather blunt; midvein dissipated into forking vein- 

 lets. The fertile portion rises above the sterile, 

 usually disappearing by midsummer ; 4 to 1 2 inches 

 high. 



Found in rich soil from eastern Quebec to Mary- 

 land and westward.
