The Sensitive and Ostrich Ferns 

 Onoclea. Pteretis. Mattaiccia. Slnithiuptcri.s 



(Last three names applied to Ostrich Fern only.) 

 It is a question whether the sensitive and ostrich fern 

 should be included in the same genus. They are similar 

 in many resjjects, but not in all. The sensitive fern has a 

 running rootstock, scattered fronds, and netted A'eins; 

 while the ostrich fern has an upright rootstock, fronds in 

 crowns, and free veins.
