Perennial. July. 



Softer and more delicate in texture, as well as more shaggy, than 

 the last. The leujlcts are smaller, more numerous, blunter, and 

 rounded at the extremity, thougli tipped with a soft bristly 

 point, and each of them, even to the smallest, has a broad con- 

 spicuous lobe, at the base of the upper margin ; the lowest of 

 all, at the uj)per edge of each main leaf, is half as long again as 

 its next neighbour, more strongly serrated, and in its lower part 

 generally pinnatijid. All the lobes and serratures end in soft 

 bristly points. Sialic, and principal rib, densely covered with 

 scales, which are narrower in ])roportion as they are higher up, 

 those on the partial ribs, or on the leaflets occasionally, being 

 almost capilhiry. Masses numerous and crowded. Core;orl)i- 

 cuhir, for the most part entire, with a central depression. The 

 outline of the whole frond is rather broader than y^. aculeahoii, 

 and the more copious, distinct, rounded, auricled Itajicts give 

 the whole a rich and elegant aspect. 



Having seen no specimen of W'illdenow's plant, nor any figure 

 being (juoted by him, I cannot be certain that we mean tiie 

 same tiling. His description however is excellent, and without 

 excej)tion. 



H. A. lohatuin. Close-leaved Prickly Shield-fern. 



Frond doublv i)iinuite; leaflets elliptical, pointed, ilecm- 

 rent, slightly crescent-shaped, somewhat serrated ; tlie 

 foremost of tbe lowest pair very laige. Stalk and mid- 

 rib scaly. Cover orbicular, umbilicated.
