328 THE BOOK OF CHOICE FERNS. 



S. Y. fissum latum — fis'-sum la'-tum (split and broad), Moore. 



A large-growing form, found near Nettlecombe, producing fronds 2ft. in 

 length and fully 2in. in breadth, deeply and irregularly cut along the margins, 

 slightly wavy, narrowed to the base, and sharp-pointed at their summit. The 

 large and irregular spore masses are produced in great abundance. — Lowe, 

 Our Native Ferns, ii., fig. 653. 



S. Y. flabellatum — fla-bel-la'-tum (fan-shaped), Moore. 



This is a constant and very handsome form, with repeatedly-branched, 

 fan-shaped fronds 6in. to Sin. long and as much across in their multifid 

 portion. In their lower part these fronds are normal, but in their upper half 

 the stalk becomes repeatedly branched, the whole forming a scarcely crested, 

 nearly flat frond. — Lowe, Our Native Ferns, ii., fig. 661. 



S. Y. GlaYei — Gla'-ve-i (Glave's), Lowe. 



In this singular form, raised from spores, the fronds, 6in. long, of which 

 the lower 4in. consists of the naked stalks, are repeatedly branched into a 

 number of almost leafless, narrow divisions, which are torn and toothed on 

 the margins. — Lowe, Our Native Ferns, ii., fig. 672. *^ 



S. Y. glomerato-Yariabile — glom-er-a'-to-var-i-a'-bil-e (heaped-up and 

 variable), Monkman. 

 One of the most interesting and beautiful forms raised from spores. Its 

 fronds, about 16in. long, have their basal 6in. naked ; they vary in width 

 across the head from 6in. to lOin., and there are seldom two fronds exactly 

 alike : most of them, however, are repeatedly branched and their leafy portion 

 is handsomely crested. — Lowe, Our Native Ferns, ii., fig. 724. 



S. Y. glomeratum— glom-er-a'-tum (heaped-up), Moore. 



A very fine and beautiful form, originally found in Jersey, with fronds 

 nearly upright, twice branched, each branch again three or four times branched, 

 the ultimate ones more or less deeply lobed, and the lobes broadly blunt- 

 toothed. Sometimes the disposition differs in the stalk branching at the 

 base of the frond, which is thus in two close parts, each being again 

 three or four times short-branched, and each series of ramifications standing' 

 in a different position, thus collectively forming a dense, globular, crispy mass.. 

 Sin. to 4in. across. — Lowe, Our Native Ferns, ii., fig. 690.
