'2. C. mojitdna (Link) ; fronds triangular tripinuate, pinnae and 

 pinnules spreading, lobes pinnatifid with linear notched segments. 

 H. F. 25. S. 24. Fronds in shape like those of Polypodmm 

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

 pinnae much the largest; their lower larger than their upper 

 pinnules. Stipe long, slender. Rhizome creeping extensively, 

 black. Breadalbane and Grampian Mountains. P. VII. VIII. P

1. A. FilLr-fcem ina ( Roth) ; frond lanceolate pinnate or pinna- 

 tin' d, pinnae linear, pinnules linear-oblong deeply serrate or pin- 

 natifid. H. F. 35. a. A. rhceticum (Roth) ; frond bipinnate, 

 pinnules toothed narrowly triangular-lanceolate convex remote 

 not connected toothed, upper ones minute confluent, clusters 

 ultimately confluent. N. 245. A. conve.rum~^Qwm. Pinnules 

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

 attachment broad ; segments gradually decreasing trom the 

 base of pinnule. /3. A. Filix-fcemina (Roth) ; 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 . 

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

 y. A. molle (Roth) : frond pinnate, pinnules toothed oblong 

 blunt or slightly pointed flat remote all connected by wing of 

 midrib or lower ones distinct, segments ovate bidentate lowest 

 with 3 teeth uppermost with 1 tooth. N. 245. Frond scarcely 

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

 decurrent base. Clusters distinct, in 2 rows. Sometimes 

 (A. trifidum Roth P) the pinnules are much less connected, 

 moderately cut, have a narrow attachment, and lobes with 

 more but connivent teeth. There are innumerable subvarieties.
