Grandiceps, WoUasto7}. (Fig. 128.) — The history of this 

 Fern is obscure, and all that is known about Grafniiceps is that 

 Mr. Swynfen Jervis, of Darhxston HaU, Staffordshire, is in pos- 

 session of the only plant in existence, and that it is one of 

 the handsomest forms of Polystichiun angulare yet discovered, 

 bearing a strong resemblance to Polystichum aculeatum variety 

 lohatum-corymhifcrum of ^loore, and very like a crested lobate 

 form of P. aculeatum in general appearance. Length of frond 

 twelve inches, width (except at the apex) from one and a half 

 to two inches; at the apex the frond branches, and these branches 

 are again divided and subdivided, their extreme apices being 

 cristate and fan-shaped, forming a circular head of about four 

 inches and a half across. ^ly thanks are due to Mr. Swynfen 

 Jervis for a frond of this splendid Fern.
