This, our only trailing fern, is found in north Jersey, but is 

 perhaps most frequent, though always local, along streams in the 

 Middle district, especially in Burlington county. It grows in 

 dense thickets, climbing up on the bushes and herbs to a height 

 of two or three feet. 



Spores Mature. — Late September intO' October or even later. 

 Fertile portion of the frond uncurling with the sterile during 

 spring; scarcely evergreen, becoming brown and dried during 

 winter. Sterile frondlets remaining green over winter, but 

 perishing the following spring along with the fertile.
