PLATE XI. B. 



Asplenium marinum, var. microdon, MooEE. Hooker. 



Aspleninm — Spleenwort. Lanceolatum — Lanceolate. 



Microdon — Small-tootlaed. 



At page 79, vol. v, of the "Natural History of British and 

 Exotic Ferns," Asplenium lanceolatum has been described, to 

 which reference is made. The present variety is a most remark- 

 able one, and was found in Guernsey in 1855 by Miss Wilkinson, 

 and an account of it published by Mr. Thomas Moore, of the 

 Chelsea Botanic Gardens. 



When first discovered it was thought to be a variety of A. 

 marinum, owing to its being so little divided: larger fronds 

 have shewn it to be an undivided variety of A. lanceolatum. It 

 is well worthy of cultivation, both being handsome and distinct. 



The fronds are pinnate, and more linear in form than linear- 

 lanceolate, and tapering to a point. The pinnae distinct below, 

 with a brief stalk, broadly-triangular in form, becoming adnate 

 above. Length of frond from nine to twelve inches. 



Sori near the margin, oblong and small. 



For fronds I am indebted to Mr. Thomas Moore, of Chelsea; 

 and to Mr. Sim, of Foot's Cray.
