1-l-i ASPIDIUM TRIANGULUJl, VAR. LAXUM. 



Aspidium — Shield Fern. Triangulum — Triangular. 



Var. laxum — Lax variety. 



In the Section Polystichum of Authors. 



An exceedingly handsome, stove, very scaly Fern, introduced 

 into this country in 1859, from spores, by Mr. E.. Sim, of 

 Foot's Cray, from .Jamaica. 



The habit is pretty, and tufted. The fronds are narrow, 

 linear, with small, sharp-pointed, triangular, or sub trap eziform 

 pinnte, and having a few large, sj^iny, recurved segments at 

 the base. 



It resembles Polystichum triangulum but has more divided 

 fronds. 



Crown erect, stout, and fawny-scaled. 



Sparingly proliferous. 



Length of frond from fifteen to eighteen inches. Colour 

 rich green. Width in widest part an inch. 



The normal form of this Fern is figured on Plate XXXI — 

 B, vol. vi, of my "Natural History of Ferns," under the 

 name of Aspidium mucronatum, Swartz. 



For fronds my thanks are due to Mr. R. Sim, of Foot's 

 Cray, Kent.
