N. splendens — splen'-dens (splendid). Synonymous witti N. acuta. 



N. trichomanoides — tricli-om-an-6-i'-des (Triciiomanes-like). A synonym 

 of iV. ramosa. 



N. tuberosa — tu-ber-o'-sa (tuberous-rooted). 



This is the common garden name for N. cordifolia, and by far the more 

 popular of the two. The species was so named by Presl, who describes 

 it in his " Tentamen Pteridographias " ; Kunze and Moore, in their respective 

 works "Index Filicum," retain the name tuberosa; and Lowe, in his excellent 

 work " Ferns British and Exotic " (vii., p. 45), states that it is also found in 

 J. Smith's " Catalogue of Ferns cultivated in British Gardens." 



N. undulata — un-dul-a'-ta (wavy), /. Smith. 



This comparatively dwarf, stove species, native of Sierra Leone, West 

 Africa (whence, according to Lowe, it was introduced into the Royal Gardens, 

 Kew, in the year 1848, by the Right Hon. the Earl of Derby), is exceedingly 

 handsome, especially when in fructification. Its fronds, which are of an 

 arching but not drooping habit, seldom exceed l|ft. in length ; they are 

 narrowly spear-shaped, and furnished with narrow- oblong, pointed leaflets 

 of a thin, papery texture, notched at the edges, and of a cheerful light green 

 colour. — Lowe^ Ferns British and Exotic, vii., t. 20. 



Like N. cordifolia and N. pluma, this species produces small tubers, 

 from which it can easily be propagated after its resting period. It is very 

 scarce in collections, owing, doubtless, to its being of deciduous habit, which 

 often causes it to be accidentally thrown away during its resting time. 



N. YOlubilis — vol-u'-bil-is (twining). A variety of N. exaltata. 



N. Zollingeriana — Zol-lin-ger-i-a'-na (Zollinger's), De Vriese. 



A Malayan species, of somewhat upright and stitF habit, differing from 

 most other kinds through its leaflets being so deeply toothed as to appear 

 bipinnatifid ; they are set a little way apart on round stalks of a woolly 

 nature, green in the early stage of development, but turning with age to a 

 dark brown colour. The fronds, of medium dimensions, and seldom attaining 

 more than l^ft. in length, are of a cheerful light colour. The rhizomes 

 (prostrate stems) are freely produced and extend a long way from the plant.
