THE root is cenit, see y of a weude? Fires, 
of a dark brown colour: the general leaves are numerous, pin- 
nated, six or eight inches in length the ribs of which are smooth, 
and of a Shitibs blackish opicte: the pinne are sessile, somewhat 
roundish, indented at the edges, placed oppositely, and consisting 
of about twenty pairs, of which the largest stands in the middle 
of the leaf; the others gradually decrease towards each extremity, 
especially the upper: the fructifications, or seed vessels, are 
_ placed on the back of the pinne or lobes of the leaf, and form a 
row of three or four on each side of the midrib: at first they are 
yellowish, and are covered with a thin membrane, which when at 
maturity bursts, and discharges the contents over the other leayes. 
It is common in this country, and is usually found on old walls 
and rocks 1 in moist and shaded situations.
