Flowering period, November to March, in favourable or mild seasons.
Arisæma Triphyllum
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. Arisæma 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. The spadix is over 3in. long, club-shaped, spotted with brown, very much so near the end. The anthers at the base of the spadix are curious, and should be examined. They are invisible until the folded part of the spathe is opened; they are numerous, arranged in a dense broad ring, sessile, and nearly black. This curious flower is produced on a stout, round scape, a foot or more in height. The leaves are radical, having a stalk a foot long. They are, as the specific name implies, divided into three parts, each being of equal length, entire, wavy, and pointed. The whole plant has a somewhat top-heavy appearance (see Fig. 16), but I never saw it broken down by the weather. It makes quick growth in spring, the scape appearing with the leaves; in late summer it dies down. It looks well in quiet nooks, but it also forms a good companion to showy flowers in more open situations; in a cut state, for dressing "old-fashioned" vases, nothing could be in better character, a few leaves of yarrow, day lily, flag, or similar foliage being all it will require.

It may be transplanted, any time from September to the end of January, into good light loam or leaf soil, 4in. or 6in. deep; if there should be a dry season during the period of growth, the plant should be well watered. To increase it, the tubers may be divided every third year, providing the growth has been of a vigorous tone. I may add, that, from its tall and not over-dense habit, there may with advantage, both to it and the plants used, be a carpet grown underneath—ivy, vincas, or sweet woodruff for some situations, and brighter subjects for more conspicuous parts of the garden, such as the finer kinds of mimulus, ourisia, alpine aster, and dwarf iris.
Flowering period, June and July.
Arum Crinitum
As may be seen by the illustration (Fig. 17), this is a most singular plant. It proves hardy in this climate if its position is selected; in other words, it is not hardy in all kinds of soils and situations, but if planted four or five inches deep, in sandy or half decayed vegetable mould, facing the south, there is little to fear either as regards hardiness or its thriving. I think, therefore, it may be called hardy. It is far more interesting than handsome, but there is at the present time an evident desire amongst amateurs to grow the various Arums, and more especially has this one been sought after; I have, therefore, introduced it amongst more beautiful flowers, and given an enlarged drawing of the entire plant, together with the spathe in its unopened state.
The plant is a native of Minorca, and was imported in 1777. In this climate it grows to the height of 18in., developing the flower with the foliage. It is produced on a stout scape nearly 1ft. high, of a pale green colour, marked with dark short lines and spotted with delicate pink dots. The folded spathe is of leather-like substance, rough, almost corky in texture; also variously marked and tinted. At the base there are a number of green lines arranged evenly and longitudinally on a nearly white ground. A little higher—the belly part—the lines are less frequent, irregular, and mixed with pink dots. Still higher, the ground colour becomes pale green, the lines dark green, and the pink spots are changed to clouded tints; the remainder of the folded spathe—to the tip—is a mixture of brown and green dots, the total length being fully 9in. When the spathe opens, it does so quickly, bending more than half its length outwards, the division looking upwards. To those who have not before seen the plant at this stage, it will prove an interesting surprise; the odour, however, is repulsive. The spathe at its widest part is 6in. broad, and tapers off to a blunt point. It is of a dark purple colour and covered with long bent dark hairs, whence the specific name. They are curiously disposed, and remind one of some hairy animal that has been lifted out of the water the wrong way as regards the direction of the hair. The spadix is comparatively small, black, and also covered with hairs. The flower should be closely watched if its peculiarities are to be fully noted, as it not only opens quickly but soon begins to wither. During the short period that the flower is open the lower part of the spathe or belly becomes filled with all kinds of flies, being held by the spear-like hairs.

The leaves have long stalks, marked and tinted in a similar manner to that of the scape. They are curiously formed and twisted, pedate or bird-foot shaped, the outer segments twice cut, lance-shaped, and turned inwards or over the main part of the leaf; the leaves are of a deep green colour, and of good substance; they seldom exceed four in number to each plant or tuber.
This curious species should, as above indicated, have a warm situation, where it will also be comparatively dry in winter. Its propagation may be effected by division of the roots of strong specimens.
