fertile branches, in most instances start separately

the Little Adders-tongue has a stem to its seed- 
bearing spike which rises above the barren frond. 
At the top of the spike begins the fructification ;

each side of the stalk supporting them. In these 
cases are the dust-like spores, which, as they 
ripen, escape through the crevices formed by the 
splitting of their little prison-houses. 
One peculiarity must be noted in the Little 
Adders-tongue. Vulgatum first sends up its 
frond in May, from which time it remains until 
the late summer, when it disappears — the root

but Lusitanicum starts into life and vitality in 
dreary January, lasts only a short two or three 
months, and perishes very early in the season, — 
even before the actual commencement of summer. 
This modest little Fern only reaches a height 
of two or three inches. It is, indeed, even more 
unpretending than Vulgatum, But its habitats
