(Mountains, Kamtschatka, Lake Baikal, Tasmania, tho Island of
Luegia, Australian jilp s , etc.
A difficult plan t to cultivate. F o u n d in dry, open, elevated
pastures and waste lands; req u irin g to be k ep t cool and moist
by a thick low vegetation, which invariably surrounds this
species. Hence the difficulty of imitating its n atural growth.
Fronds herbaceous, the sterile and fertile hranchcs being
distinct.
Fronds solitary; the sterile branch p in n a te ; pinnæ lunate or
fan-shaped, from four to seven p a irs; margin somewhat crenate,
occasionally partially fertile. The fertile branch pinnate or
b ipinnate, the contracted rachiform divisions fleshy.
Foots stout, fleshy, and brittle. Stipes erect and smooth,
bearing a two-branched frond, the one sterile and the other
fertile.
Veins of the b a rre n frond repeatedly forked, radiating from
the base, and terminating within the margin.
Fructification sessile, erect, in two rows along each segment.
Spore-cases smooth and spherical, bursting transversely; when
mature, golden brown in colour.
T he plan t perennial, b u t the fronds annual.
T h e re are two distinct varieties.
T h e variety rutaceum has a broader b a rren branch, which
is triangula r in form and tivice divided.
T he variety moorei, (Pla te L X V I .—B,) named after Mr.
Thomas (Moore, an indefatigable and well-known cryptogamie
botanist, is similar in its fronds to the normal form, with the
exception of its edge being deeply incised, giving the frond av-ery
handsome appearance. This variety has been found in some
abundance near Crosby Ravensworth, Westmoreland, by Mr.
Clarke, gardener to Mr. Wilkinson Dent.
L en g th of frond from eight to ten inches; colour a light
yellowish green.
The normal form may he procured of any Nurseryman.
The illustrations are from fronds forwarded b y Mr. Clarke.
