 herbarium. Found likewise by Mr. E. Forster. 



Perennial. July. 



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

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

 rounded at the extremity, though 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 j the lowest of 

 all, at the upper edge of each main leaf, is half as long again as 

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

 generally p'mnatijid. All the lobes and serratures end in soft 

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

 scales, which are narrower in proportion as they are higher up, 

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

 almost capillary. Masses numerous and crowded. Cover orbi- 

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

 outline of the whole /ro«(Z is rather broader than A. aculeatum, 

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

 the whole a rich and elegant aspect. 



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

 being quoted by him, I cannot be certain that we mean the 

 same thing. His description however is excellent, and without 

 exception. 



8. A. lohatum. Close-leaved Prickly Shield-fern. 



Frond doubly pinnate ; leaflets elliptical, pointed, decur- 

 rent, slightly crescent-shaped, somewhat serrated ; the 

 foremost of the lowest pair very large. Stalk and mid- 

 rib scaly. Cover orbicular, unibilicated.
