 (listinet. See Fig. 26. 



A C.-V. fissum (divided). Very dwarf in habit, with pinnules 

 rather broader than those of the type, which are deeply and

 lia\iiig fronds a foot or more long, with very ample pinnules 

 deeply incised, light green. A'igorous.

 more or Ifss eiori;;ated in outline, 3in. to 4in. across; piinudes

 The archniu character gives this form a most ilistinct appe;- ranee 

 A very Hue variety. 



A. C.-V, rotundum founded). Pinnules nsuallv round, without 



tin- ciniLifMnii base of the m.nnal form; neither are the fronds 



so bn.ad. Ule of Man. Variable in its habit. 

 A. C.V. undulatum (wavy).* fcomlg dense, compart, havin-

 again ; segments about ^in. long, ^in. deep, dimidiate, the 

 lower line upcurved, the upper nearly straight, slightly crenate.
