90 POLYPODIUM SCOLOPEJ^DROIDES. 



size and form. Fronds growing horizontally from an erect very 

 scaly rhizoma. The scales dark brown in colour. Margin of 

 frond and under side of all the veins covered with a copious 

 minute white pubescence. 



Veins usually simple, occasionally forked, and always anas- 

 tomosing next the midrib. 



Sori large, conspicuous, copious, eventually confluent; biserial. 



Length of frond about nine inches; width three-quarters of 

 an inch; colour bright shining green. Fronds only naked for 

 the length of half-an-inch. 



Mr. Cooling, of Derby, has raised a number of plants from 

 spores, which are undoubtedly the true Poly podium scolopen- 

 droides. 



My thanks are due to Mr. J. Smith, Curator of the Royal 

 Gardens, Kew, and to Mr. Joseph Henderson, of Wentworth, 

 for fronds of this species. 



It does not appear to be in any Fern list excepting Mr. 

 E. Cooling's, of Derby. 



The illustration is from Mr. J. Smith's frond.
