This plant has exactly the habit and appearance of JtJiynum
Eilix-foemina ; and hence Mr. Newman, in proposing to make it
the type of a new family group, has called it Fseudathynum
alpestre. It is a very elegant plant, the fronds reaching from a
foot to a foot and a half high, and growing terminaUy from a
short creeping rhizome. The fronds are lance-shaped, narrowed
to the base, and twice pinnately divided. The pinnæ are lanceolate,
acuminate; the pinnules lanceolate, acute, and deeply
pinnatifid, with oblong sharply-serrated segments. The son are
produced either at the sinus of the lobes of the pinnule, and
thus form two distinct and distant Unes paraUel to, and on
each side the midrib; or the little lobes bear about four sori,
disposed in a row, on each side their midvein, and so near
too-ether as to become confluent into one mass.
This species, hitherto known as a native of Switzerland, has
been gathered by H. C. Watson, Esq., in the Highlands of
