ii6 FERNS AND THEIR ALLIES 



in form and ternate, the three primary divisions 

 stalked and pinnately decompound, being cut 

 into many narrow lobes. 



It is frequently found growing with the 

 Common Grape Fern in shady places, al- 

 though preferring more open situations, and 

 it is more common near the coast. The sterile 

 frond appears in July and is said to be ever- 

 green. 



Both sterile and fertile portions are long- 

 stalked, the fertile the longer. At the summit 

 of the taller stalk is a branching fruit-cluster 

 similar to that of the Common Grape Fern, but 

 less compound. It matures in September and 

 October. 



Bolrychium teniatum, sub-var. intermedium {Bo- 

 trychiiim obliquum infermedium) . 



The sterile portion is very broadly trian- 

 gular and similar to var. obliqiiimi, but often 

 larger and more fleshy. The ultimate seg- 

 ments are- divided somewhat more, are shorter 

 and less pointed, with minutely toothed mar- 

 gins. 



It is found frequently, growing in old pastures 

 and thickets. 



The fertile portion is also similar to that of 

 obliquum, being quite compound.
