ATHYRIUM FILIX-FGEMINA. 



71 



form, with fronds sixteen inches in length, and six inches in 

 width in the widest part of the frond. A fragile delicate Fern. 

 Pinnce descending to the centre of the frond, and then slightly 

 ascending to the apex, linear-oblong, acuminate, the upper ones 

 irregular in size; alternate from the base to the tip of the frond. 

 Pinnules usually large, broad, and much laciniated, the upper 

 half of the frond very various in form, extraordinarily laciniated, 

 depauperated, various in shape and size, sometimes wanting, 

 and sometimes the apices of the pinnae terminating in naked 

 points. Sori very irregular, and very sparingly distributed over 

 the under surface of the frond. I am indebted to Mr. Padley 

 for the illustration.

Laveyanum, Ivery. (Figs. 376 and 377.) — A remarkable 

 Fern. Fronds twenty-eight inches long, and three inches 

 and a half -wdde in the broadest part, and only half an inch 

 wide for the eight inches next the apex. The lowest six 

 inches destitute of pinnae, for the next eight inches distant, 

 then crowded and overlapping each other to the apex. From 

 the centre of the frond upwards, the rachides branching 

 abruptly into a cluster of three pinnules, the pinnules being 

 deeply divided, various in form, and dentate. I am indebted 

 to INIr. Ivery, of Dorking, for fronds.
