A. R.-m. trifoliatum— trif-ol-i-a'-tum (three-leaved), Lowe.

A. (Euasplenium) salicifolium — E u-as-ple'-ni-um ; sal-ic-if-ol'-i-um 

 (Willow-leaved), Linnoeus. 

 A stove species, of medium dimensions, native of the West Indies, with 

 fronds 1ft. to lift, long, 6in. to 9in. broad, borne on stalks 6in. to 12in. long, 

 and furnished with numerous distinctly- stalked and often horizontal leaflets 

 of a thin texture, on which the sori (spore masses) fall short of both edge 

 and midrib.— Hooker, Species Filicum, hi., p. 112. Nicholson, Dictionary of 

 Gardening, i., p. 134. 



A. (Euasplenium) Sanderson! — Eu-as-ple'-m-um ; San-der-so'-ni 

 (Sanderson's), Hooker. 

 This pretty and very distinct, greenhouse species (Fig. 125) is a native 

 of Natal, Zambesi Land, and Johanna Island. Its slender, graceful fronds, 6in. 

 to 9in. long, lin. broad, and usually proliferous (bud-bearing) at their extremity, 

 are borne on green stalks lin. to 2in. long and slightly scaly. They are 

 furnished with from twelve to twenty pairs of horizontal pinnas (leaflets) about 

 Jin. long, shortly stalked, of a peculiar dimidiate form (fully developed 

 on one side of the midrib and scarcely at all on the other), and deeply 

 toothed on the upper edge, the lower one being nearly straight, quite entire, 

 and curved backwards. The texture is thin and papery, and the oblong sori 

 (spore masses) are disposed from one to three to each leaflet. The small, 

 size of the fronds and the well-defined characters of its pinnas give this Fern 

 a very elegant aspect and render it most interesting and useful for small
