POLYSTICHUM ANGULARE.

Braciiiatum, Moore. (Fig. 77.) — Found in I860, in Devon- 

 shire, by Mr. C. Hillman, a collector of Ferns. The fronds, 

 which are from twelve to twenty-four inches in length, are 

 pyramidal in form, being much the broadest at the base. The 

 lowest pair of pinnae are sometimes so large as to take the 

 appearance of branches. The sterile pinnules are obtuse, with 

 an obtuse auricle, which is profoundly and acutely serrated. 

 The fertile pinnules vary from ovate to trapeziform. The 

 anterior basal pinnules are double the size of the others, and 

 sometimes doubly auricled. My thanks are due to Messrs. 

 Stansfield, of Todmorden, for fronds.
