LASTREA DILATATA.

Mr. P. Neill Fraser, and receiving the present name at the 

 request of the discoverer. Length sixteen to eighteen inches; 

 narrow — width five inches. Stipes very sparingly scaly and 

 thin. Substance thin, pinnules leafy, solid, dentation small. 

 Apex of frond somewhat wedge-shaped. The inferior basal 

 pinnules of all the pinnae, except near the apex, twice the size 

 of the superior ones. My thanks are due to Mr. P. Xeill 

 Fraser for fronds.

SucciSA, Lowe. (Fig. 265.) — A somewhat robust, compact, 

 and upright-growing variety found by myself at Dale Abbey 

 in Derbyshire, in August, 1864. Length of frond about fifteen 

 inches. Pinnae approximate and ascending. Pinnules crowded 

 and leaf-like. More or less normal, except as regards the apex 

 of the frond which is as if clipped off, making a flat and broad 

 termination to the fronds. The plant had a dozen fronds on 

 when found, and has since sent up several others, all of which 

 have this peculiarity. Succisa is an interesting and remarkably 

 distinct variety, and when growing, from its habit, shews off 

 its square-ended fronds to the most advantage. 



Naxa, Newman. — Found near Settle, in Yorkshire, by Mr 

 J. Tatham; near Ilfracombe by the Rev. J. M. Chanter; at 

 Challacombe, Exnioor, in Devonshire; Tarbot, Dumbarton-
