Clapliam. A handsome form. Fronds broadly-lanceolate, and 

 undivided at the apex. l^innoc linear-oblong, ending in a 

 small multifid tuft. Pinnules ovate-acute, distinct and pro- 

 foundly pinnatifld below. Lobes narrow-oblong. Teeth fine, 

 even, and acute. Remarkable for the very regular toothing, 

 and for its less decidedly multifid character than some other 

 varieties.

Latifolium-multifidum, Stansjield. (Fig. 479.) — Found at 

 Aberfeldy, in Perthshire, in 1863, by Mr. A. Stansfield, Jun., of 

 Vale Nursery, Todmorden, and Mr. J. Fielden. A slender 

 plumose form of latifolium, with crowded pinnae beautifully 

 crested. Length of fi-ond twelve inches, width four inches 

 at the centre of the frond, where widest, and narrowing to 

 the base and apex gradually and symmetrically. The three or 

 four basal pairs of pinnre somewhat distant and descending, 

 the others crowded and ascending, touching each other, their 

 apices furcate and crested; pinnules crowded, also touching each 

 other, and feathery. The illustration is from Messrs. Stansfield. 



Plumosum, Moore. — Fronds thirty inches long, and twelve 

 inches broad. Very broadly-lanceolate, and distinctly tripinnate. 

 Pinnae in the centre of the frond from five to six inches long, 

 and two inches and a half broad. The longer pinnules an 

 inch and a quarter long, nearly parallel-sided, and the apex 

 shortish-acuminate. Somewhat distant below, and crowded 

 above. Pinnules ovate-acuminate, overlapping, divided into 

 distinct secondary pinnules which- are half an inch long, linear, 

 and inciso-pinnatifid; segments narrow, having linear-acute teeth.
