NEPHROLEPIS DAVALLIOIDES. 



ft 



Pinnae, lower portion opposite or sub-opposite, upper portion 

 mostly alternate. There are about sixty pairs of pinnse on 

 each frond. 



Fronds pendant and very graceful. Pinnae rather distant 

 and horizontal. 



Sori circular; about forty pairs on each pinna. 



Indusium reniform, and situated immediately within the 

 margin of the lobe. 



Rhizoma wiry, creeping, and. scaly, to which the fronds are 

 adherent in fascicles. 



Length of frond from thirty-five to fifty-five inches; colour 

 bright green. 



There is a very beautiful variety of this species, having its 

 divisions deeply cut into lobes, as Mr. Sim remarks, much 

 in the same way as the elegant varieties of Polypodium vulgar e, 

 (that is, cambricum and semilacerum.) 



There are very few monstrosities, as they are termed, 

 amongst the exotic Ferns, but as there is an increasing desire 

 to cultivate our foreign species, no doubt ere long many in- 

 teresting varieties will be added to our collections. 



For a plant my thanks are due to Mr. Parker, of Holloway; 

 and for fronds to Mr. Henderson, of Wentworth, and to Mr. 

 Ingram, of the Royal Gardens, Windsor. 



It is in the Catalogues of Messrs. Veitch, of Chelsea; 

 Rollisson, of Tooting; Sim, of Foot's Cray; Jackson, of 

 Kingston; Booth, of Hamburg; E. G. Henderson, of St. 

 John's Wood; and Cooling, of Derby. 



The variety is in Mr. Sim's Catalogue. 



The illustration is from my own plant.
