This very beautiful Fern is exceedingly rare in cultivation 

 in this country, it is similar to Gymnogramma Clirysophylla, but 

 more slender, and smaller in size; the pinnse are also broader 

 at the base, and considerably more attenuated at the apex. In 

 general appearance it has a character half-way between G. 

 sidplmrea and G. clirysophylla. The accuminated apex of the 

 frond is more drawn out than in G. chrysoplmjlla, and the 

 farinose powder on the under side of the frond is in colour 

 lighter than that of G. clirysophylla, and darker and more yellow 

 than that of G. sulphurea. 



The frond rises out of a short erect rhizoma, and is scarcely 

 ever more than ten inches in length, and three and a half 

 inches across in the widest part, usually six inches in length. 

 The colour of the stipes and midrib is a pale reddish brown, 

 being much lighter, and has not quite so much of the polished 

 appearance of G. clirysophylla. The colour of the frond, on 

 the upper side, is a f)ale dull yellowish green, whilst beneath 

 it is densely covered with a brilliant farinose powder of a light 

 yellow colour. 



Mr. Moore remarks that the sori are often crowded, and con-
