 throughout central and aouthcru rvirowo to Greece, Italy, and Spain. In Africa it b found in Algeria, in Madeira, and 

 in the Arorca. In Asia it occur*, according to Lcdcbour, in the Cauca*n% on the Siberian side of the Ural Mountains, 



and in Turciiitmnin ; and npaiii is found in Aaia Jfinor (HI. //cot/r), at JV^rx>utii. and iu >\Mi,ini IVmia (//i. ZiaJby

Gaudcx thick, abort, tufted, often decumbent, scaly at tlic crown. S&ites lanceolate -acuminata^, 

 pale ]>ur[)lish-brown, sinning, finely rcticulato-vcnose. Fibres sliort^ branched, numerous, dark brown, 



Stipes averaging about onc-thinl tlio length of the froml, but varying fmm alwnt one-fourth to 

 one-half its entire length ; usually clothed with pale tawny contorted subulate scales, sometimes 

 smooth, purplish -brown, darkest at the Kise; terminal, and adherent to thecaiulcx, Ilnchis, or more 

 correctly midrib, stout, scaly behind when young, often dark-coloured IjoIow. 



Vernation circitiate. 



Fronds from about four inches to two feet or upwards in length, narrow elongate-lanceolate, or 

 broadly linear, or oblong strap-»sha]>cd» normally entire, or slightly sinuous on the margin, with the 

 apex more or less attenuated, and terminating in an acute point, and having the base cordate ; piano, 

 fleshy or coriaceous, deep rich green. The varieties deviate in unnumbered forms, by the laceration or 

 undulation of the margin, the multilld dilatation of the apex, the branching (often repeated) of the 

 stipes and midrib, the loss of the cordate lobes at the base, and the arrest of longitudinal developments 



Venation ]xirallelo-furcatc ; that is, the veins which spring from the midrib are one, two. or three 

 times forked near the base ; and the veinUts thus produced extend side by side nearly to the margin, 

 and almost at a right angle, terminating in club*-shapcd apices. In the enlarged base of the frond, 

 the furcations are mom numerous.
