The Alternate-leaved Spleen- 
wort is a small delicate plant, 
having a tufted caudex, to 
which the fronds are terminal 
and adherent. The numerous 
fronds grow up in the spring, 
and flourish during the sum- 
mer, but usually perish in the 
winter, so that the species is 
but sub-evergreen ; they are 
from three to six inches high, 
narrow linear, somewhat widen- 
ed at the base, pinnate, with 
distant, alternate, narrow, 
wedge-shaped pinnae, which 
taper gradually at the base 
inco a short slender stalk, by 
which they are attached to the 
rachis. The stipes is slender, 
about half the length of the 
frond, smooth, purplish at the 
base, the rachis being, for the 
most part, green. The pin- 
nx are ascending, toothed or [Asplenium germanicum.]
