Obtusl'm, Stansfield, MS. (Fig. 27.) — A pretty, small-fronded 

 variety, though rather larger than the normal form, distinguished 

 by the rounded edges of the lobes, which are very obtuse. 

 Gathered in North Wales, by Mr. Stansfield, of Todmorden, 

 and in Devonshire, by Mr. Hillman. Somewhat inconstant. 



Omnilacerum, Moore. (Plate VII — B.) — Found by ^Ir. 

 E. T. Bennett, near Goodrich Castle, Ross, Herefordshire. This 

 exceedingly elegant, and distinct variety is still very rare. 

 Somewhat in the way of Camhricum, yet quite distinct 

 from that variety. It has the lobes irregularly pinnatifid, the 

 lobules being narrow and jagged. It differs from Camhricum 

 in the narrow and less-crowded lobes, and in being fertile. 

 Length of frond from twelve to eighteen inches. Habit 

 nearlv erect. Lobes narrowish next the rachis, widening towards 



^ • • • 



the middle, and tapering beyond. Deeply cut into narrowish, 

 often very attenuated acute lobules, which, towards the centre 

 of the lobe, are often much projected, more particularly 

 from the lower margin. The deeply serrated lobes are 

 sometimes nearly bipinnatifid. Usually the frond is considerably 

 longer than in Camhricum, the lobes having their di\dsions 

 more acute, and more regular, than in that variety. A constant 

 and beautiful Fern. A^'hilst young, the divisions are sharply 

 and deeply toothed — exceedingly saw-edge-like; when stronger 

 these teeth lengthen very much into very slender lobules, wliich 

 are again a little torn, or toothed.
