ASPLENIUM MARINUM. 



PuLCHRUM, Moore. — Found on rocks on the bank of the 

 River Dart, near Totness, by Mr. C. Scott. Not unlike 

 ramosum in appearance, yet less marked in character. Dwarf, 

 not exceeding eight inches in length. Pinnae brief, oblong- 

 obtuse, truncate, indistinctly auricled, dovibly crenate on the 

 margin, and in mature plants the primary crenatures are so 

 deep as to become sublobate.

AcuTUM, Moo7'e. (Figs. 535 and 536.) — Fronds two feet long, 

 lax, being distantly pinnate. Pinnse broadest at the base, and 

 one inch and a half long. The anterior margin auricled, and 

 the posterior side cuneate. The pinnae gradually narrowing to 

 the apex, which is sharp-pointed. Crenate. Having more 

 acute pinnse than in the normal form. In the basal half of 

 the frond the pinnse are shorter, and very variable in shape; 

 in the upper half, except at the apex, longer and narrower. 

 Pinnse simple. Stipes ebeneous. Found in Jersey and in 

 Guernsey by the late Mr. C. Jackson; Plymouth Hoe by Mr. 

 J. Barker; Dartmouth Castle and Croyde, in Devonshire, by 

 the Rev. J. R. Chanter. The illustration is from Messrs. 

 Stansfield's fronds.
