ATHYRIUM FILIX-FCEMINA. 



Fig. 324. — Pinnae. 



Defectum, Wollaston. (Fig. 3.'24.)— Found in July, 1860, 

 at Drummelzien, near Brougliton, by iNIr. P. Neill Fraser. 

 Length of frond sixteen or seventeen inches; width very 

 variable, sometimes as much as six inches. No two pinnae 

 alike in shape, and very various in size. Mr. Wollaston 

 remarks that this variety is the exact counterpart of the 

 variety varians in Polystichum angulare, and therefore it is a 

 pity that name has been already taken up. The fronds are 

 sometimes split on the rachis, and become twin. My thanks 

 are due to Mr. P. Neill Fraser for fronds.

DiGiTALE, Loivc. (Fig. 325.) — A multifid variety, raised 

 from spores by Mr. Edwin Cooling, of Derby. This variety 

 is not unlike the Cynodon dactylon, or Creeping Finger Grass, 

 hence its name. Dlgitale most nearly resembles BaJfourii, 

 differing in the pinnai and pinnules being narrower, and in 

 the linear digitate multifid apices. A lax form. Length of 

 frond twenty-six inches, width only five inches. Pinnules
