N. ae. angustipinnulum — an-gus-tip-in'-nul-um (having narrow leafits), 

 Moore. 



The peculiarity in this variety, originally found near Cushendall, in 

 Antrim, consists in the pinnules (leafits) being more confluent, the lobes 

 being irregularly shortened, and the teeth more evidently awned than in the 

 type. — Lowe, Our Native Ferns, i., p. 333. 



N, 86. ramosum — ra-mo'-sum (branched), Clajjham. 



This singular form, originally found at Hackness, only differs from the 

 typical species in having twin fronds joined together at the base. — Loive, 

 Our Native Ferns, i., p. 333. 



N. (Sagenia) alatum — Sag-e'-m-a ; al-a'-tum (winged), Wallich. 



A very distinct, robust-growing, stove species, native of Assam, Singapore, 

 Java, and Borneo, producing from a creeping rhizome (prostrate stem) fronds 

 2ft. to 3ft. or more long, borne on rather distant stalks 1ft. to 2ft. long, but 

 winged a long way down, sometimes almost to the base ; they are oblong 

 in shape, and furnished with four or five pairs of distant, oblong or strap - 

 shaped leaflets, on which the small and numerous sori (spore masses) are 

 scattered without order, being covered by a small, heart-shaped involucre. —

N. (Lastrea) albo-punctatum — Las'-tre-a ; aF-bo-punc-ta'-tum (white- 

 spotted), Desvaux. 



This distinct and pretty, evergreen, stove species, native of Guinea, Natal, 

 Angola, Fiji, &c., possesses an entirely original character, and at first sight 

 has all the appearance of an elegantly-variegated Fern, owing to the upper 

 surface of its leaflets being dotted all over with small white spots. Its fronds, 

 9in. to 12in. long and 4in. to 6in. broad, are produced from a slender, wide- 

 creeping rhizome (prostrate stem), and borne on naked, jointed stalks of 

 a greyish colour. The pinna3 (leaflets) are spreading, 2in. to 3in. long, Jin. 

 broad, and cut half-way or more down to the rachis (stalk of the leafy 

 portion) into oblong, blunt, entire lobes. The fronds are of a soft, papery 

 texture and of a very dark green colour above, thus showing to perfection 

 the small, white dots with which they are adorned. The sori (spore masses)
