The Green Shield of Saturnalia

Habit: Evergreen shrub or small tree that can reach 8-10 m in height. Branches: Patent; the young ones are pubescent, becoming cylindrical and glabrous in the second year. Bark: Smooth and glabrous, initially green and grey-blackish when mature, tending to peel and roll on itself; it has sparse and sparse lenticels. The overwintering buds are conical and pointed (2-3 mm), green and glabrous, flanked by rounded flower buds and a terminal bud. Leaves: Persistent (lasting 2-3 years), leathery, alternate, simple and briefly petiolate, with small deciduous stipules. The leaves of the lower branches have oval or elliptical, wavy blades, with a whitish margin and conspicuously toothed-spiny (6-8 spines per side) as a natural defense against the bite of herbivores; The leaves of the upper branches and old shoots have an entire blade, with a smooth margin and a pointed tip. Both surfaces are glabrous: the upper one is dark green and shiny, the lower one is opaque and lighter. Flowers: Dioecious plant with double, tetramerous (4-merous) flowers, gathered in multi-flowered clusters (2-3) with a short stalk at the axil of the previous year's leaves. The calyx is persistent with 4 lobes; the corolla is formed by 4 white petals that grow together at the base and are edged with red. The male flowers have 4 stamens; the female flowers show a pistil with a superior ovary surmounted by 4 almost sessile stigmas. Pollination is mainly entomophilous (performed by bees). Fruit: Globose, stalked and umbilicate drupes. When ripe they turn a bright red colour (adaptation to attract disseminating birds such as blackbirds and thrushes). They contain 3-5 bony, single-seeded, plano-convex kernels (pyrenes) with 3-5 dorsal ribs. Flowering: May - June.

Chorological type: Subatlantic/Submediterranean. Distribution in Italy: Present in all regions, but now rare and confined to the wild. Habitat: Typical component of the undergrowth (shrub layer) in beech, fir-beech, and oak-hornbeam forests, while it takes on an arboreal habit when growing in open spaces. It prefers semi-shaded locations and moist, well-drained, nutrient-rich soils, often decalcified and acidified, between 0 and 1400 meters above sea level.

Genus (Ilex): The name derives from the ancient Latin name used for the holm oak (Quercus ilex L.), establishing a morphological parallel due to the strong similarity in the spiny leaves of the two plants.

Species (aquifolium): Derived from the Latin words acus or acutus (needle, sharp) and folia (leaf), literally meaning "leaf with sharp needles," referring to the sharply prickly margin.

Toxic medicinal species. The berries (drupes) and leaves are highly toxic to humans. Accidental ingestion of the drupes causes severe inflammation of the gastrointestinal and renal systems.

In the past, the leaves and bark (rich in ilicin) were used as a bitter tonic, diuretic, antirheumatic, and above all as a powerful slow-release febrifuge. Before the widespread use of quinine, preparations (such as medicinal wine) were used to treat intermittent malarial fever. Some related species of the Ilex genus contain caffeine-like substances and are used in stimulating infusions (such as maté).

Due to its extraordinary tolerance to urban air pollution, it is widely cultivated in cities to create impenetrable defensive hedges. The chromatic contrast between the glossy leaves and the red fruits makes it the quintessential ornamental symbol of the Christmas holidays.

Holly boasts a rich symbolic tradition. The ancient Romans used sprigs as protective talismans against evil during the Saturnalia and gave them to newlyweds as a wish for prosperity. The Druids of Britain considered it a sacred plant capable of protecting from the harsh winter and, if thrown at a wild animal, taming it. The Etruscans considered it a powerful and dangerous boundary plant, to be confined outside the home. In the Middle Ages, the Germanic peoples hung its branches on stable doors to protect livestock from witchcraft. Overseas, the Native Americans discovered by Columbus planted it near their huts as a spirit-chasing amulet and wore its leaves in battle as a badge of valor and courage. Due to its deep connection to the history of the region, the holly leaf frequently appears in the civic heraldry of numerous municipalities. The Bergamo dialect name "spinaràc" links it to butcher's broom (Ruscus aculeatus). Both plants were hung by farmers at the base of corn drying racks (spalére) or in the cellars beneath the "baldüc" (where cured meats were aged) to create an insurmountable mechanical barrier against mice (rat or sorèch).
