This species has been cultivated at the Royal Gardens, Kevv, 

 since the year 1823. 



It is a native of the East Indies, China, Jiipan, and the 

 Island of Java. 



A much more fleshy-looking Fern than JSf. rupestris. 



An evergreen stove species. 



Both barren and fruitful fronds are of a shining green colour. 



Sterile frond oblong-ovate, obtuse, being decurrent at the base, 

 fertile frond linear, and also decurrent at the base. 



Length of sterile frond from three to four inches, of fertile 

 frond from four to eight inches; attached to a creeping scaly 

 rhizoma. 



About three rows of sori, which eventually become confluent. 

 The sori reddish in colour, and confined to the upper half of 

 the frond; the midrib is generally seen as a green belt between 

 the two rows of sori. 



The veins and costa being immersed within the frond, are 

 almost invisible. 



The starry-pubescence is very apparent on the shining smooth, 

 fronds of this species, giving it the look of being covered with 

 snow-crystals. 



Plants have been received from Mr. Henderson, of Went- 

 worth, and from Messrs. Booth, of Hamburgh; and fronds from 

 the former gentleman and Mr. Sim, of Foot's Cray.

 Hamburgli; Bollisson, of Tooting; Masters, of Canterbury; A. 

 Henderson, of Pine-apple Place; Veitch, Jun., of Chelsea; 

 Osborn and Sons, of Fulham; and Sim, of Foot's Cray. 



This and the last succeed best if planted amongst moss in 

 shallow M'ire baskets.
