S. Y. c. Forsteri— Fors'-ter-i (Forster's), Druery. 



This sub-variety is quite distinct, its branched stalks, with no leafy 

 portion to speak of, terminating in dense, rounded crests of a pale green 

 colour. — Druery, Choice British Ferns, p. 137. 



S. Y. Claphamii— Clap-ham'-i-i (Clapham's), Moore. 



A singular and distinct form, found at Grassington, Wharfedale, Yorkshire, 

 with fronds l^ft. long, 2in. broad, furnished at their base with a pair of 

 narrow, sharp-pointed lobes. They are crisped and irregularly cleft along 

 their margins, their summit is branched, and the branches are repeatedly 

 forked.— Lowe, Our Native Ferns, ii., fig. 727. Nicholson, Dictionary of 

 Gardening, iii., p. 393. 



S. Y. Cliftii— Clift'-i-i (Clift's), Lowe. 



This variety, originally found in North Wales, is very distinct and pretty. 

 Its fronds, about 1ft. long, have their lower half naked, the leafy portion 

 being narrow, of a leathery texture, with a smooth, even margin ; it terminates 

 in a large, compact, much-branched head, very leafy, and uncut on the margins. 

 — Lowe, Our Native Ferns, ii., fig. 640. 



S. Y. COnglomeratum— con-glom-er-a'-tum (massed together), Lowe. 



Though somewhat resembling the better-known S. v. glomeratum, this 

 variety, found at Truro, differs essentially from that form in being of a less 

 leafy character, that is, more deeply cut at the summit and more or less 

 depauperated (impoverished) between the crest and the plain portion of the 

 fronds, which is almost reduced to the stalk itself. This variety is perhaps 

 better known as the Truro form of glomeratum. — Lowe, Our Native Ferns, 

 ii., fig. 691. Druery, Choice British Ferns, p. 137. 



S. Y. COngregatum— con-greg-a'-tum (collected), Lowe. 



This is a very distinct, large-growing, multifid variety. The stalk is 

 twin-branched near the base, then naked for about 3in., when it branches 

 again ; the summit of the leafy portion of each frond expands into a large, 

 multifid, crisped, narrowly- cleft, compact, bushy head.— Lowe, Our Native 

 Ferns, ii., fig. 772.
