S. Y. Yariegatum — var-i-eg-a'-tum (variegated), Moore. 



There are several varieties of this Fern, with foliage of a more or less 

 distinctly-marked nature, each form bearing in commerce the name of its 

 discoverer ; thus we have variegatum Claphami (Lowe, " Our Native Ferns," 

 ii., t. 44b), a form of nornial dimensions, beautifully variegated with white, 

 but not quite permanent. Then there is variegatum Elworthii (Lowe, " Our 

 Native Ferns," ii., fig. 738), which is a handsome permanent variety of a narrow 

 normal form, much and conspicuously variegated. Another form, of dwarfer 

 habit than either of the above-named, is variegated with yellowish-white and 

 not very permanent ; this is called variegatum Willisonii, and was found wild 

 in North Yorkshire. — Lowe, Our Native Ferns, ii., p. 332 ; New and Bare 

 Ferns, p. 58. 



S. Y. Wardii — Ward'-i-i (Ward's), Clapham. 



This, very distinct form, of dwarf habit, was raised from spores by 

 Mr. Glave, of Scarborough. Its singular fronds are borne on long stalks and 

 form a small, massive, multifid head with a round outline, composed of 

 repeatedly scarcely-branched, more or less crowded, very crispy parts, of which 

 the marginal ones are cut into very irregular lobes, and these are very 

 irregularly narrow-toothed and faintly marginate. In the close, moist atmos- 

 phere of a glass structure the fronds of this pigmy variety, seldom 6in. high, 

 become profusely studded all over with tiny bubil-plants. — Lowe, Our 

 Native Ferns, ii., fig. 677.
