186 BOTRYCHIUM 



LANCE-LEAVED GRAPE FERN:* 



Botrycliium lanceolatum, var. angustisegmentum. 

 The lance-leaved grape fern consists of a sterile 

 and fertile portion surmounting a common stalk. 

 The sterile division is triangular in outline^ seated 

 near the top of a long^ slender stalky with two or 

 more pairs of pinnae, the lowest pair being the 

 largest, lobes acute; variable in its cutting; vein- 

 lets forking from a continuous midvein. The fer- 

 tile portion rises but slightly above the sterile; 3 to 

 9 inches high. 



Found from Nova Scotia to New Jersey, Ohio 

 and Lake Superior. 



* The Botrychiums are an exceedingly variable group, 

 puzzling even to the expert botanists. For this reason 

 no attempt has been made in this book to enumerate all 

 the different varieties.
