Polypodium alpestre (p. 205).—There are some 
Variations of this Fern recorded, of which flexile is 
a very permanent and decided variety. Its leaflets 
ar e much shorter, with only six or eight pairs of 
leafits, consequently rendering the outline of the 
fronds much more narrow and flexible ; the leafits are 
stalkless and united at the base; stem either very 
short or entirely absent. Lanceum differs chiefly in 
outline of form and in its leafits being subfalcate; tri- 
Pinnatum, more uniformly tripinnato, and the leafits 
long; incisum, cut; interruptum, stopped; laciniatum, 
slashed ; prxmorsum, bitten off.
