a flattened rachis (stalk of the leafy portion) into five or six pairs of somewliat 

 fan-slia^Ded, short -stalked leaflets of a thick, fleshy texture and pale milky-green 

 colour ; each leaflet is scalloped (toothed) on the 

 edge and usually more or less lobed at the base. 

 The fertile peduncle usually equals and sometimes 

 exceeds the sterile frond when fully developed. The 

 panicle of fructification is bipinnate (twice divided to 

 the stalk), of a close nature, spear-head -shaped, and 

 usually lin. to 2in. long. See Fig. 5. — Hooker^

Alps, with a stout stem lin. to 4in. long, bearing 



a sessile (stalkless) frond only lin. to 2in. long, triangle-shaped, and cut 

 down to a flattened stalk into several close, somewhat egg-shaped leaflets 

 on each side, the lower ones of which are deeply cleft. The fertile 

 peduncle (stalk) equals the barren frond when mature, and terminates in 

 a close, bipinnate (twice divided), spear-shaped panicle lin. to 2in. long. —

This species is very variable, and several of its distinct forms are 

 usually considered and catalogued as species.
