POLYSTICIIUM ANGULARE. 



Frond ovate-acuminate; as in Linsare, the pinnules being narrow, 

 interrupted, and alternate; much depauperated and very 

 various in size and shape. The difference between the present 

 form and Lineare consists in it being rigid, proliferous, and in 

 being much more linear near the rachis of the frond. The 

 three or four pairs of pinnules next the rachis on each pinna) 

 are almost or quite wanting, except the midvein, which remains 

 as a spine, the next one or two pairs as a forked spine, beyond 

 which are small pinnules with cuneate bases, the pinnules 

 becoming larger and more perfect the further they are removed 

 from the base of the pinnae. The superior basal pinnule is 

 very long but linear, sometimes however only represented by 

 a spine. Rachis and stipes very scaly. My thanks are due to 

 the Rev. Charles Padlcy for fronds.

Proliferum-Wollastoni, Moore. (Fig. 104.) — This very 

 handsome variety has been described at page 80. It is closely 

 allied to Proliferum. It was found near Ottery St. Mary, in 

 Devonshire, by Mr. George B. Wollaston, of Chiselhurst, and 

 subsequently at Barnstaple, by Mr. Jackson. Although un- 

 doubtedly distinct, it is one of the forms of Proliferum, and 

 has been thought to be a variety deserving a figure. I am 

 indebted to Mr. Wollaston for fronds.
