아룸 마쿨라툼-[정명] Arum maculatum L.

Arum maculatum, commonly known as cuckoopint, jack-in-the-pulpit and other names (see common names), is a woodland flowering plant species in the family Araceae. It is native across most of Europe, as well as Eastern Turkey and the Caucasus.

Description

The leaves of A. maculatum appear in the spring (April–May in the northern hemisphere, October–November in the southern hemisphere) and are 7 to 20 cm long. These are followed by the flowers borne on a poker-shaped inflorescence called a spadix, which is partially enclosed in a pale green spathe or leaf-like hood. The spathe can be up to 25 cm high and the fruiting spike which follows later in the season may be up to 5 cm. The flowers are hidden from sight, clustered at the base of the spadix with a ring of female flowers at the bottom and a ring of male flowers above them. The leaves may be either purple-spotted (var. maculatum) or unspotted (var. immaculatum).

Above the male flowers is a ring of hairs forming an insect trap. Insects, especially owl-midges Psychoda phalaenoides, are attracted to the spadix by its faecal odour and a temperature up to 15 °C warmer than the ambient temperature. The insects are trapped beneath the ring of hairs and are dusted with pollen by the male flowers before escaping and carrying the pollen to the spadices of other plants, where they pollinate the female flowers. The spadix may also be yellow, but purple is the more common.

In autumn, the lower ring of (female) flowers forms a cluster of bright red, berries up to 5 cm long which remain after the spathe and other leaves have withered away. These attractive red to orange berries are extremely poisonous.

The root-tuber may be very big and is used to store starch. In mature specimens, the tuber may be as much as 400 mm below ground level.

Many small rodents appear to find the spadix particularly attractive; finding examples of the plant with much of the spadix eaten away is common. The spadix produces heat and probably scent as the flowers mature, and this may attract the rodents.

Arum maculatum is also known as cuckoo pint or cuckoo-pint in the British Isles and is named thus in Nicholas Culpeper's famous 17th-century herbal. This is a name it shares with Arum italicum (Italian lords-and-ladies), the other native British Arum. "Pint" is a shortening of the word "pintle", meaning penis, derived from the shape of the spadix. The euphemistic shortening has been traced to Turner in 1551.

The plant is propagated by birds dispersing the seeds by eating the berries. As a seedling the plant has small light green leaves that are not glossy like the mature leaves. At about 5 months its leaves grow larger and glossier. At one year old all of the leaves become glossy and die back. The next year the plant flowers during summer.
