POLYSTICHUM ANGULARE. 



seven inches and a half across the basal pair of pinna?, the next 

 pair only six inches, the next six pairs about five inches, then 

 suddenly reduced to an inch, except a solitary pinna of three 

 inches and a half in length. The apex much branched, spreading 

 to the width of six inches. In the basal portion of the frond 

 the pinna; are long, and crowded together, their apices more 

 or less linear. In the middle portion of the frond the pinnae 

 are interrupted, being reduced to a long narrow lobe. The 

 pinnules on the basal pair of pinna) are much larger than the 

 others, and the inferior and superior pinnules are very similar 

 in size; these pinnules are long and narrow, with almost rounded 

 apices, having a deeply-divided auricle, which is almost wanting 

 on the other pinna?, except near the apex of the frond. These 

 pinnules are somewhat triangular in form, having a cuneate base, 

 and here the lobe becomes a marked feature, being itself more 

 or less deeply cut and densely spiny; the whole of the pinnules 

 are densely spiny. Stipes and rachis scaly. I am indebted to 

 Mr. Charles Elworthy, of Nettlecombe, for fronds.
