(» ANEMIA ADIANTIFOLIA. 



Fronds bipinnate, except at the base, where tripinnate. 

 Pinnae, two together at the base of the frond, then alternate, 

 apex of the frond attenuate. Pinnules, basal ones deeply 

 divided, wedge-shaped at the base, and sharply dentate on the 

 margin, the other pinnules acutely wedge-shaped at base, their 

 apices rounded. Fertile frond tripartite, the two opposite seg- 

 ments contracted, erect, constituting two sporangiferous racemes. 

 The pair of fertile pinnse at the base of the frond are situated 

 on long slender stalks, and usually there is a third fertile pinna 

 situated immediately above with a sterile pinna, the rest of the 

 pinnse being barren. 



Rachis and stipes very slender, and copiously hirsute. 

 Pinnules also hirsute. 



Length of frond twelve inches. 



Veins forked and free. 



Sporangia oval, attached to the base, opening vertically on 

 the exterior side. 



I am indebted to Mr. J. Smith, of the Royal Gardens, Kew, 

 for the fronds from which the present illustration has been 

 made.
