LASTREA FILTX-MAS. 



Fig. 196. 



Erosa, Clowes. (Fig. 196.) — Found at Lodore,near Keswick, 

 by Miss Wright, aiad at AVindermere, by Mr. Clowes. A sub- 

 permanent variety. The fertile portions of the frond are variously 

 erose (abbreviated,) being irregularly contracted. Pinnules 

 biserrated, oblong-obtuse. The basal sterile pinnules rigid and 

 not erose. Occasionally the whole fronds are abbreviated, the 

 fronds more lax, and the pinnae and pinnules distant and 

 irregular in size and semi-depauperated. My thanks are due 

 to Mr. Clowes, for good examples. 



Fig. 197. 



CnispA, Sim. (Fig. 197.) — A form of Lastrea pro- 

 pinqua. A densely leafy distinct fern, dwarf, crispy, and 

 compressed-fronded. Length from eight to twelve inches; 

 colour dark green. Almost erect in habit, briefly stalked, 

 oval-lance-shaped fronds of from four to six inches wide. 

 Pinnaj and pinnules overlapping each other, those next the 

 rachis so much overlay as frequently to quite conceal it. 

 Pinnules slightly twisted. I am indebted to Mr. Sim, of Foot's 

 Cray, for fronds.
