FiMimiATUM, Allchin. (Fig. 642.) — Fovincl in Guernsey by 

 Dr. Allchin, A distinct form of the marginotum section, 

 with two kinds of fronds. The broader fronds are six 

 to nine inches long, and three quarters of an inch Avide; the 

 base contracted and truncate, frequently with small separate 

 lobes, the margins irregularly fimbriated, crenate-lobate, with 

 the lobes undulated and creuate. Sori mostly exterior to the 

 excurrent membrane. The narrower fronds are nine to twelve 

 inches long, and only a quarter of an inch wide; so narrow 

 is the leafy portion, that on either side it is only of the same 

 width as the rachis itself: its margins are finely fimbriated. 

 My thanks are due to Mr. P. Ncill Frascr, of Cannon jVIills 

 Lodge, Edinburgh, for a plant.
