greenhouse or a cold frame, and by the end of the following May they
will be ready to plant out. A well-drained position is important.

Flowering period, November to March, in favourable or mild seasons.

Arisaema Triphyllum.

_Syns._ A. ZEBRINUM _and_ ARUM TRIPHYLLUM; _Common
Names_, THREE-LEAVED ARUM _and_ JACK-IN-THE-PULPIT;
_Nat. Ord._ ARACEAE.

A hardy tuberous-rooted perennial from North America. I will at once
explain that the above leading name is not the one generally used here,
but in America, where the species is common, botanists have adopted it;
besides, it is, as will be seen from the following description, very
distinct from other Arums. The Syn. _Arisaema zebrinum_, as given,
belongs really to a variety of _A. triphyllum_, but the type is marked
in its flowers zebra-like, and there are many shades and colours of it,
therefore both or either of the names may be used for the different
forms, with a fair degree of propriety, as in fact they are.

There is a doubt with some as to the hardiness of this plant; in my mind
there is none whatever. It is no stranger to frosts in its habitats, but
I do not found my conviction on anything but my experience of it. It has
been grown fully exposed for two winters, and sometimes the frosts must
have gone as far down as the roots.

There is nothing showy about this plant, but there is something which
stamps it as a fitting subject for a garden of choice plants; its bold,
dark green foliage and quaint-looking flowers render it desirable on the
score of distinctness. It has, moreover, a freshness upon which the eye
can always linger. The flowers are in general form like the calla-lily;
the upper part of the spathe, or sheathing leaf, which is really the
calyx, is, however, more elongated, pointed, and hooked; otherwise the
spathe is erect, slightly reflexed just above the folded part, giving
the appearance of a pair of small lobes; this--the calyx--is really the
most conspicuous part of the flower; in the belly it is beautifully
striped with broad lines of a purplish-brown colour, which shade off to
an inch of green in the middle, when they form again, and continue to
the tip of the spathe, which will be 4in. to 6in. long, and nearly 2in.
broad at the widest part; these lines run between the ribs, and, as
before hinted, they are of various colours, such as brown, purple, pink,
and green. The ribs are nearly white, and the green parts are very pale.
