PLATE XXIX. B. VOL. II. AND PLATE L. VOL. I. 



This species was figured on plate L. vol. 1, and described 

 on page 145 of that volume. When it was then described it had 

 not fructified in England; since then Mr. Downs, of Ilfra- 

 combe, has forwarded me fertile fronds; and within the last two 

 months my own plant has also put on fertile fronds. Under these 

 circumstances it has been deemed desirable to give an illus- 

 tration shewing the manner of fructification, especially as the 

 fertile fronds are very different in form, being contracted so 

 as to become almost linear. For further description see vol. 1, 

 page 145. 



The illustration is from Mr. Downs' frond.
