Cristato-gracile, Moore. (Fig. 101.) — Found at Ottery St. 

 Mary, in Devonshire, by the late Mr. Charles Jackson, of 

 Barnstaple, and also in the same county by Mr. R, J. Gray, 

 of Exeter. A most lovely and graceful Fern. It is of the 

 same normal form as Gracile, another species found in Devon- 

 shire, by Mr. G. B. Wollaston, and described at page 101, but 

 differs in being crested. A much-cut variety, with ovate- 

 attenuate bipinnate fronds. Pinnules small, narrow, oblong- 

 acute, and hardly-auricled, variable in form, and some linear; 

 having an inciso-scrrate margin. The apices of the fronds, as 

 well as those of the pinnte and pinnules, are crested. Mr. 

 Gray's form of this variety is a very good one. It is about 

 tAvelve inches in length, and only two inches and a half wide 

 in the widest part, and the apices of all the pinnule's are 

 semi-transparent, owing to the green epidermis not extending 

 to their extreme ends, and being very conspicuous from their 

 unusual breadth. My thanks are due to Mr. E,. J. Gray, of 

 Exeter, and to Mr. Swynfen Jervis, of Darlaston Hall, for 

 fronds. The illustration is from near the base of the frond. 



AcuTiLOBUM, IVollaston. (Fig. 102.) — Found near Barnstaple, 

 in Devonshire, by the late Mr. C. Jackson. Normal in length, 

 (that is twenty-four inches.) The fronds deltoid, subtripinnate. 

 The pinnae are lanceolate, the lower pair being longer than the
