V. 2166. PL V. Fig. 1. 



Corresponds closely with V. 2157, but differs in the greater size 

 of the frond, of which this is a fragment, and in the fact that the 

 ultimate segments are slightly broader. Closely associated with 

 the fragments on this piece of rock are portions of what may 

 possibly be the rhizome of the same species. Cf. PI. IV. (V. 2157) 

 and PL V. Eig. 11 (V. 2156). Ecclesbourne. Rufford, Coll. 



V. 2156. PL V. Fig. 3. 



In Fig. 3a we have an exceedingly graceful ? frond of roughly 

 pentagonal form and compact habit. It represents a further 

 increase in the breadth of the ultimate segments, but is still 

 entirely in accord' with the general character of the species. 



Fig. 3b shows part of a large frond with a Well-marked flexuous 

 rachis. Cf. PL V. Fig. 2 (V. 2155a). Ecclesbourne. Ruffori Coll. 



V. 2155fl. PL V. Fig. 2. 



Yery similar as regards breadth of segments to V. 2157, PL IV. 

 The rachis is distinctly flexuous, and the general habit of this 

 and other specimens is strikingly similar to that of Anemia 

 adiantifolia, Sw.

V. 2243. PL V. Fig. 4. 



A slight increase is apparent in the breadth of the segments, and 

 some of them appear to be obtusely rounded at the apex rather 

 than acute. In each lobe of the pinnae are several palmately- 

 placed veins. The first glance at this specimen and Fig. 2 of 

 the same plate (V. 21d5a) suggests two specific forms, but on 

 close inspection of the two specimens a difference in breadth of 

 the ultimate divisions appears to be the only real distinction, 

 and, in view of the correspondence in habit, this alone is hardly 

 of sufficient importance to necessitate a separate species. Eccles- 

 bourne. Rufford Coll. 



V. 2731. PL III. Fig. 5. 



This affords a good example of a small and compact type of 

 ? frond, which differs only in size from the larger and commoner 

 specimens. On the same piece of rock is a piece of rhizome,
