downwards as mucli or perhaps more than it does towards
the point. The pinnæ generally stand opposite, and are
narrow, tapering, and pinnatifidly divided, bearing their
fructification almost close to the margins of the segments,
and generally very abundantly.
In this species the divisions of the fronds are flat, not
revolute, as in L. Thelypteris, which most resembles it. Each
segment or lobe has a distinct and shghtly sinuous midvein,
which is alternately branched, the branches simple or divided,
and bearing the spore-cases in clusters near their extremity.
This plant loves shade, and is found most luxuriant in
woods, occurring also on mountainous heaths. It may be
considered a common plant in England, Wales, and Scotland
; but in Ireland is much more rare. It is an effective
plant for shady rock-work, and, when established, grows
freely.
Besides the name we have here adopted, this Eern has
borne the following titles :—Aspidium Oreopteris, Polypodium
Oreopteris, Polypodium montanum, Polystichum montanum.
