POLYSTICHUM AKGULARE. 



Affine, Moore, {Polystichum affine, Wollaston.) (Fig. 84.) 

 — An exceedingly distinct variety, found at Hartley, in Hamp- 

 shire, by Mr. G. B. Wollaston, of Chiselhurst, and considered 

 by the discoverer to be a new species. The fronds are dark 

 in colour, firm in substance, and lanceolate in form, having 

 the apex attenuated. Pinnules ovate-falcate, somewhat convex, 

 bluntly auricled, and indistinctly serrated. Stipes long. The 

 form is pretty, and the aspect is that of a slender form of 

 Polystichum aculeatum. My thanks are due to Mr. Wollaston, 

 of Chiselhurst, for fronds. 



Curium, Moore, {Semitripinnatum, Moore.) — Found near 

 Nettlecombe, Somersetshire, by Mr. Elworthy. A pretty and 

 curious dwarf Decompositum-looking Fern, with short triangular 

 fronds of from six to eight inches in length, and five inches 

 in width at the base. The pinnae, which are crowded and 

 alternate, are somewhat irregular. The pinnules overlap each 

 other, and when least developed are like JBiserratum; the more 

 developed ones are more or less pinnatifid, when they somewhat 

 resemble Plumosum. The upper half of the frond soriferous. 

 The posterior pinnules of the basal i)air of pinnse are enlarged, 

 being pinnate at the base, and profoundly pinnatifid upwards, 

 giving the plant a character and resemblance of Lastrea
