S. Y. Cooling'ii — Coo-ling'-i-i (Cooling's), Lowe. 



This is one of the few varieties known to be proliferous. It .is a very 

 handsome plant, of dwarf habit, with short fronds branching near the base ; 

 their stalks are branched a second time, while the leafy portions are repeatedly 

 branched, their divisions being wavy and finger-like, forming a ball-like 

 object seldom more than Gin. in height. Numerous little bulbils are found on 

 the edge of their leafy portion. — Lowe, Our Native Ferns, ii., fig. 744. 



S. Y. COronare — cor-o-na'-re (crowned), Lowe. 



A beautiful variety, raised from spores by Mr. E. J. Lowe. It has more 

 or less oblong-egg-shaped fronds about 9in. long, usually lobed on one side 

 only at the base, slightly wavy along the margins, and notched below the 

 contracted part, where the stalk divides into a numerously -branched, flat head, 

 4in. across. — Lowe, Our Native Ferns, ii., fig. 718. 



S. Y. Cousensii — Cou-sens'-i-i (J. Schott Cousens'), Moore. 



A wild find of very remarkable character, the fronds being repeatedly 

 branched like those of S. v. Wardii, but forming much larger, rounded heads 

 of foliage, consisting of innumerable small, fan-shaped lobes, of which the late 

 Thomas Moore counted 166 in one frond, each being again subdivided into 

 smaller lobes. The plant becomes a spherical mass and occasionally bears 

 marginal bulbils. — Druery, Choice British Ferns, p. 138. 



S. Y. crenato-lobatum — cre-na'-to-lo-ba'-tum (jagged-lobed), Moore. 



A very interesting variety, normal in size and general outline, 

 though its fronds, which along their margins are distinctly jagged and lobed, 

 are sometimes widest at their middle. They attain from 1ft. to IJft. in length 

 and their abundant and prominent spore masses show on the upper surface, 

 where they appear very large. — Lowe, New and Rare Ferns, p. 56 ; Our 

 Native Ferns, ii., fig. 594. 



S. crenatO-multifidum — cre-na'-to-mul-tif'-id-um (jagged and multifid), 



Moore. 



This handsome form is said by Lowe to have been gathered by several 



persons in various limestone districts. The fronds are conspicuously jagged 



along the margins and have a marginal line on their under-surface ; they are
