An evergreen stove Fern.
Native of Mexico, wliicli it has been found hi tbe temperate
and cold regions, at a height of from two to seven thousand
feet above the sea, by Schiede and Liehmann.
In form it is very like Polypodium, vulgäre.
The peculiar feature of this handsome F ern is that the
under side is dotted over with conspicuous brown scales, which
are a great contrast on the pale green of the frond.

quarters. Colour bright bluish green.
Round the edge of the frond there is a thickened rim, and
on the upper side along the margin, there is a row of circular
white scales.
Sori a single row on each .side the midrib, very large,
reddish, usually about ten or twelve pairs; eventually confluent
and joining each other.
The frond for illustration was kindly communicated by IMr.
