A VERY interesting pigmy Fern from Guernsey, having been 

 discovered in the year 1854 growing in sandy loam near Petit 

 Bot Bay, by Mr. G. "Wolsey, and since found in other places 

 in that island. 



This species may be called a winter Fern, the fronds coming 

 up in winter, and arriving at maturity about the middle of 

 January. 



An indigenous Fern, with annual fronds. 



Found in Portugal, Spain, France, Italy, Sicily, Greece, the 

 Mediterranean Islands, Tangiers, Algiers, the Canaries, the 

 Islands of Madeira, Teneriffe, Azores, and Guernsey. 



The fronds are thick, fleshy, and pale green in colour. 

 Sterile and fertile branches on the same stem; the sterile 

 branch linear to linear-lanceolate in shape, tapering below to 

 where it joins the fertile branch; fertile branch longer, erect,
