POLYSTICHUM ANGULAKE. 



above, large; the pinnules long, deeply serrated, and minutely 

 spinose. The inferior pinnules, especially of the basal pair of 

 pinnae, longest, and the superior basal pinnule twice the length 

 of the remainder, conspicuously auricled, the auricle of the 

 superior basal pinnule distinctly stalked. My thanks are due 

 to Mr. G. B. WoUaston, of Chiselhurst; Mr. C. Elworthy, of 

 Nettlecombe; Mr, Swynfen Jervis, of Darlaston Hall; the 

 Rev. Charles Padley, of Bulwell Hall; the Rev. F. Mules, 

 of Marvvood; Mr. Daniels, of Ruthin Castle, Denbighshire; 

 and Mr. Edwin Cooling, of Derby, for fronds. I can see 

 but little difference between this and Subtrijyinnatum.

Athyrioides, WoUaston. (Fig. 153.)— Subscqviently to writing 

 a description of this variety, on page 101, Mr. WoUaston, of 

 Chiselhurst, forwarded me a frond, and although before it was 

 deemed unnecessary to give an illustration, since then I have 

 thought it advisable to refer again to the variety, and to have 

 a wood-cut illustration executed, thinking that without one there 

 -would be a great chance of those who are not quite conversant 

 with this species, being misled without this additional aid.
