 Rohertianum, small, short, very finely divided. Lower pair of

 natifid. — H. F. 35. — a. A. rhmticum (Both) ; frond Mpinnate 

 pinnules toothed narrowly triangular-lanceolate convex remote 

 not connected toothed, upper ones minute confluent, clusters 

 ultimately confluent. N. 245. A. conxexum Newm. Pinnules 

 long, naiTow, with deflexed edges, enclosing the clusters ; their 

 attachment broad ; segments gradually decreasing from the 

 base of pinnule. — /3. A. Filix-fcemina (Eoth) ; frond bipin- 

 nate, pinnules pinnatifid oblong-lanceolate bluntish flat remote 

 not connected, segments oblong patent with lateral and ter- 

 minal sharp teeth. N. 237. Frond much divided dark green. 

 Pinnules much narrowed at their base. Clusters distinct. A. 

 latifolium (Bab.) is apparently only an extreme state of this. —

 blunt or slightly pointed flat remote all connected by wing of

 with 3 teeth uppermost with 1 tooth. JV. 246. Frond scarcely 

 more than pinnate, bright green. Pinnules attached by a broad 

 decurrent base. Clusters distinct, in 2 rows. Sometimes 

 (A. trifidum Eoth ?) the pinnules are much less connected,

 more but connivent teeth. — There are innumerable subvarieties.
