82 POLYPODIUM CRENATUM. 



continual series of interesting objects are ever before the eye. 



The Polypodium crenatum is a beautiful Fern which was 

 raised at Kew, in the year 1835. 



A native of the West Indies, St. Domingo, Martinico, and 

 St. Crucis. 



An evergreen stove species. 



The fronds are pinnate, the pinnge pubescent, entire, oblong 

 ovate-acuminate, membranous and crenate on the edge. Very 

 short petioles. 



Sori medial, and very conspicuous. 



Hachis and stipes green. 



Fronds lateral, adherent to a short creeping rhizoma. 



Length of frond from eighteen inches to two feet; colour 

 pale green. 



More generally known as the Goniopteris crenata. 



A rare Fern in cultivation in England. 



It does not appear to be in any of the English Nurserymen's 

 catalogues; it is, however, in that of Messrs. Booth, of Hamburgh. 



I have not been able to procure this species; my thanks are, 

 however, due to Mr. Henderson, of Wentworth, for a beautiful 

 fertile frond. 



The illustration is from Mr. Henderson's frond.
