POLYSTICHUM ANGULARE. 



Mr. Moore as a form of Decompositiim. The pinnules are almost 

 linear, profoundly lobed, and having a distinct anterior auricle. 

 The basal pinnse are the largest, and on these the pinnules on 

 the posterior side are considerably larger and more divided 

 than is the case with those on the anterior side. It is un- 

 necessary to figure this variety.

CoRYMBiFERUM, Moore. (Fig. 72.) — Found at Whitby, in 

 Yorkshire, by Mr. Willison. A handsome and constant variety, 

 less marked in its peculiarities than Kitsoiiiw, yet having the 

 same general character. It is corymboscly branched at the 

 apices of the fronds, but less compoundly so than in KitsonicB. 

 The lower portion of the frond is almost normal, the pinnules 

 being small. My thanks are due to Mr. G. B. Wollaston, of 

 Chiselhurst, for illustrations. 



FuRCATUM, Moore. — Found at Gittisham, near Ottery St. 

 Mary, Devonshire, by Mr. G. B. Wollaston; at Barnstaple, in 

 the same county, by Mr. H. F. Dempster; and at Nettlecombe, 

 in Somersetshire, by Mr. C. Elworthy. A dwarf interesting 

 form. The fronds are nearly normal, the distinction consisting 

 in the apex of the frond, or the apices of the pinnae, or of 

 both, being forked once or twice beyond the usual acuminated 

 or attenuated portion; the lobes in these portions are brief 

 and short, and are confined to the extreme tip. No illustration 

 is needed, as a description will suffice.
