ance, but larger, the stipes more densely scaly, but tile tuft of scales ag 
the base of the stipes so conspicuous in I if. inoeaualig, is wanting in this-

btipes, raohis, and both surfaces of the frond more or less covered with 
whitish or light brown silky hairs, with a small tuft of scales at the base 
of the stipes. The outline of the frond is triangular, the apex pinnatifid, 
and below it 2 to 4 pairs of distant pinnae which are again once or twice 
divided; color of the frond a much lighter green than the other two species. 
It is found on damp rocks under shade, and always with a Southerly aspect.
