branched and the tips of each branch forked, forming a tassel about 3in. 

 wide. — Lowe, Our Native Ferns, ii., p. 121, fig. 456. 



A. F.-f. F. imbricatum — im-bric-a'-tum (imbricated), Ivery. 



An exceedingly interesting form, differing from A. F.-f. Fieldice in having 

 the pinnas (leaflets) of its fronds conspicuously imbricated (overlapping). It 

 was raised from spores by Mr. Ivery, of Dorking, and is tolerably constant. 

 — Lowe, Our Native Ferns, ii., p. 143, fig. 492. 



A. F.-f. F. pumilum— pu'-mil-um (small), Moore. 



This very pretty sub-variety, of small dimensions, is particularly striking, 

 for its elegant fronds, seldom above 1ft. in length and Jin. " broad from 

 their base to their point, have their extremity rounded. The leaflets are 

 crowded, and some of their pinnules (leafits) occupy an ascending, while 

 others occupy a descending, position, much in the same way as those of 

 A. F.-f. Fieldice, of which the present plant appears to be quite a miniature 

 form. — Lowe, Our Native Ferns, ii., p. 51, fig. 343. 



i^.. F.-f. flexuosum — flex-u-o'-sum (having pinnas disposed in a zigzag 

 manner), Moore. 



A singular and pretty form, of medium growth, found wild at Winder- 

 mere. It differs from all other known forms by the flexuose character of 

 its rachis (stalk of the leafy portion) and in the grotesque way in which the 

 pinnas (leaflets) are twisted. The fronds, 1-Jffc. long, are quite Gin. wide 

 throughout. — Lowe, Our Native Ferns, ii., p. 49, fig. 341. 



A. F.-f. Fraserii — Fra'-ser-i-i (Fraser's), Lowe. 



This variety, probably the handsomest of all the broad-fronded ones 

 known, was originally found wild in Larrington Glen, Lanarkshire. Its 

 fronds, 3ft. or more long and lOin. broad, are of a deep green colour. They 

 are furnished with pinnas (leaflets) Sin. long and about ljin. wide. The 

 pinnules (leafits), about fin. long and Jin. broad, are blunt- pointed, entire, 

 and fringed on the sides with short teeth, which give the whole frond the 

 appearance of being imbricated, for each pinna fairly overlaps the preceding 

 one.- — Lowe, Our Native Ferns, ii., p. 52, fig. 345.
