ASPLENIUM.

The most remarkable varieties are three which are 
much valued in ferneries. 
Yar. multifidum has the ends of the pinnse divided 
again and again, which gives it a crested appearance, 
like that of Filix-mas cristatum. 
Yar. crispum is a dwarfed plant, curled and puckered 
in every part, so as to resemble curled parsley more than 
any other fern. 
Var. incisum , where the pinnules are very deeply cut, 
so as to give a feathery appearance to the fronds. 
Var. convexum is so distinct as often to be regarded 
as a separate species. It is more elegant in all its pro- 
portions ; its leaflets smaller and more slender, and the 
veining is more compound in the larger leaflets. 
Var. latifolium, a broad, stronger-growing variety ; 
pinnules larger and more crowded, irregularly lobed. 
Var. molle is erect, with dwarfed fronds, tapering 
much to the apex and to the base, its leaflets are con- 
nected by a wing to the secondary rachis. 
Var. marinum , fronds small lanceolate, very elegantly 
tapering above and below, spreading horizontally, the 
sori very short, and much curved ; leaflets oblong and 
bluntly toothed. 
In ferneries all these varieties flourish w r ell, provided 
room is allowed for their roots to spread. 
36. Asplenium Ceterach, L. Scaly Spleen wort. 
Caudex short, thick. Fronds tufted, lanceolate, pinnate, 
smooth above, densely scaly below. Scales tawny, tapering, 
overlapping each other. Leaflets broad, ovate, horizontal, 
blunt. Veins branching, and uniting before they reach the 
margin. Sori short, oblong. Involucre very narrow, some- 
times obsolete.
