THE COMMON POLYPODY. 



short, the leafy portion partially wanting, aud its place supplied by the midvein. or other minor veins, 

 which project and form curious potato. The fronds are frequently much less, though very irregularly 

 developed, but the projecting vein or veins seem constant It was found in Ireland, by Dr. Allchin. 



IC. wmilacerum : this is the most compound of nil the/ertiie forms of this species, ami is permanent 

 under cultivation. Hie fronds are clongatc-ovatc, very beautifully and symmetrically divided, tho 

 primary lobes being themselves lobed, and, in some instances, the lobules again divided or serrated. 

 It is known generally as tho 'Darglo* Fern. Sometimes tho fronds come merely serrated, and they 

 occur in various degrees of development. The name seems to have been giveu by Link, in allusion to 

 the lobed condition of the lower half of the frond. 



17. ca,nbricum : this is by far the most bcnutiful of all known varieties of Polypodium ; it is also 

 the most compound, under all conditions uniformly barren, and permanent under cultivation. The 

 primary lobes are crowded, overlapping, and somewhat Crisped ; they are deeply pinnatilid, aud tho 

 lobules are again lobed, the lobulcte being toothed. The whole frond is oblong, or ovate-oblong, with 

 the lowor two or three pairs of lobes scarcely smaller than those on tho middle portion of tho frond, 

 which gives squareness or angularity to the base. A detached lobe itself forma a fair miniature of a 

 frond of the variety xcrrattwu
