N. (Eunephrodium) elatum — Eu-nepli-ro'-dl-um ; e-la'-tum (tall), Baker. 



A stove species, of large dimensions, native of the Mauritius, and readily 

 distinguished by its oblong-spear-shaped fronds, oft. to 4ft, long and l^^ft. to 

 2ft. broad, produced from a wide-creeping rhizome and borne on grey, downy 

 stalks about 1ft. long. They are of a moderately firm texture, dark green on 

 both surfaces, and densely downy on the ribs and edges. — Hooker^ Syno-psls 

 Fllicim, p. 502. 



N. (Lastrea) elongatum — Las'-tre-a ; e-lon-ga'-tum (elongated). A 

 variety of N. Filix-mas. 



N. (Lastrea) Elwesii — Las'-tre-a ; El-wes'-i-i (Elwes's), Baker. 



A greenhouse species, of medium dimensions, native of Sikkim, in general 

 habit much resembling N. concinnum. Its oblong-spear-shaped fronds, however, 

 are borne on very short, slightly downy stalks ; they are of moderately firm 

 texture and bright green and smooth on both surfaces. The small sori 

 (spore masses), disposed on the margins of the leaflets, are covered with tiny, 

 smooth involucres of a fugacious nature. — Hooker^ Synopsis Filicum, p. 497. 



N. (Lastrea) eriocarpum — Las'-tre-a ; er-i-oc-ar'-pum (woolly-fruited). 

 Synonymous with N. odoratum. 



N. (Lastrea) eriocaulon — Las'-tre-a ; er-i-oc-au^-lon (woolly-stemmed). 

 Baker. 



The distinctive character of this stove species, native of Rio Janeiro, 

 resides in the woolly nature of the stalks of its fronds, which are densely 

 clothed with narrow, spreading scales of a rusty-brown colour. Its fronds, 

 oblong-spear-shaped and bipinnatifid (twice divided half-way to the midrib), 

 are 2ft. to oft. long, of a parchment-like texture, bright green on both surfaces, 

 and slightly downy underneath. The medium-sized sori (spore masses) are 

 disposed on the veins, and are covered with small, fugacious involucres, — 

 Hooker, Synojjsis Filicum, p. 495. 



N. (Lastrea) erythrosorum — Las'-tre-a ; er-yth-ros-o'-rum (having red 

 sori), Hooker. 



This greenhouse species, of medium dimensions, native of Japan and 

 China, produces from a thick, underground-creeping stem, broadly spear-shaped
