Plate 22. Nat. size, b Pinnule, c Sorus, enlarged. 
Crown procumbent, and like the base of the stipe clothed 
in abundant linear shining brown scales three-quarter inch 
long. Frond herbaceous, scented, deltoid, three-pinnatifid, 
six to nine inches long, four to six inches broad, with a 
channelled stipe which is glabrous below, with a tuft of 
scales at the base ; but upward it is like the rachis and 
whole frond finely villose on both surfaces. Pinnae widely 
lanceolate, the lower largest and deltoid, three inches long, 
two inches broad, with the pinnules on the lower side larger 
and more cut. Pinnae cut to the rachis into oblong, ovate, 
blunt, pinnatifid pinnules, which are separate below, but 
connate above ; those in the lower pinnae stalked, and again 
cut into similar pinnatifid segments, with minutely crenate 
blunt lobes. Sori numerous, near the mid-rib ; indusium 
large, light coloured, persistent, horse-shoe shaped, but with 
one side longer ; bristly with white hairs. 
In form the indusium approaches that of the Athyrium 
section of Asplenium. 
Baker’s description indicates a rather larger plant, but the 
above is from Mr Bolus’ specimens, and confirmed by the 
living plants at Rosehaugh.
