this, we fear, no longer exists. Other forms are recorded, but 
none of value. All the species are thorough evergreens. To 
come now to the species which afford us really good material, 
we may start with 
The Maiden-hair Spleenwort (A. trichomanes). 
This pretty species is very widely distributed, and is found 
on old walls, on stony dykes and hedgebanks, and on rocks. 
Its fronds are simply pinnate, the black midrib sometimes 
over a foot in length, but usually about half that size, bearing 
two fairly even rows of oval-stalked divisions, on the backs 
of which the linear fructification of the species appears. 
Culture as previously indicated. The chief superficial difference 
between this and A. viride is that the latter has a light 
green midrib, to which, moreover, the pinnae are firmly attached 
in life and death, while those of A. trichomanes fall off when 
decay sets in. A. trichomanes has been fairly generous in 
varieties, especially since the whole family is chary of change.
