POLYSTICHUM ANGULARE.

Fig. 76.— Small Frond. 



Variaxs, Wollaston. (Fig. 76.) — Introduced by Mr. G. B. 

 Wollaston, of Chiselliurst. The fronds, which are from twelve 

 to twenty-four inches in length, are pyramidal in outline. The 

 pinnae approximate, opposite below, alternate above, variously 

 interrupted, mostly short and obtuse, and frequently furcate; 

 sometimes wanting: extremely irregular in its development. 

 Colour a lovely grassy green. Very scaly. Pinnules varying, 

 sometimes ten pairs, and perchance the next pinna with only 

 one pair, or even merely the ultimate pinnule. My thanks are 

 due to Mr. Wollaston for fronds.
