'''Holly''' ('''''Ilex''','' {{pron-en|ˈaɪlɛks}})<ref>''Sunset Western Garden Book,'' 1995:606–607</ref> is a  [[genus]] of approximately 600 [[species]] of [[flowering plant]]s in the [[family (biology)|family]] '''Aquifoliaceae''', and the only living genus in that family.

Holly berries are somewhat{{Clarify|date=February 2010}} toxic and will cause vomiting and/or diarrhea when ingested by [[human|people]], partly due to the ilicin content.  The fatal dose is estimated to be around twenty berries for adults. However they are extremely important food for numerous species of [[bird]]s, and also are eaten by other wild animals. In the fall and early winter the berries are hard and apparently unpalatable. After being frozen or frosted several times, the berries soften, and become milder in taste. During winter [[storm]]s, [[bird]]s often take refuge in hollies, which provide shelter, protection from [[predator]]s (by the spiny leaves), and [[food]]. The flowers are sometimes eaten by the [[larva]] of the [[Double-striped Pug]] [[moth]] (''Gymnoscelis rufifasciata''). Other [[Lepidoptera]] whose larvae feed on holly include ''[[Bucculatrix ilecella]]'' (which feeds exclusively on hollies) and [[The Engrailed]] (''Ectropis crepuscularia''). Holly is commonly referenced at [[Christmas]] time.  Also see: [[wreath]] for information on how the holly plant is used in [[Christmas]] wreaths.

Having [[evolution|evolved]] numerous species that are [[endemism|endemic]] to islands and small mountain ranges, and being highly useful plants, many hollies are now becoming rare. [[Tropical]] species are especially often threatened by [[habitat destruction]] and [[overexploitation]], and at least two have become [[extinct]], with numerous others barely surviving.<ref name=iucn>[[International Union for the Conservation of Nature and Natural Resources]] (IUCN) (2007): ''2007 IUCN Red List of Threatened Species'': [http://www.iucnredlist.org/search/search.php?freetext=ilex&modifier=phrase&criteria=wholedb&taxa_species=1&redlistCategory%5B%5D=all&country%5B%5D=all&cty_default=1&aquatic%5B%5D=all&aqu_default=1&regions%5B%5D=all&reg_default=1&habitats%5B%5D=all&threats%5B%5D=all&redlistAssessyear%5B%5D=all&growths%5B%5D=all ''Ilex'']</ref>

Evergreen or deciduous trees or shrubs: lvs. alternate, petioled, with small, caducous stipules, sometimes spiny: fls. dioecious, usually in rather few-fld. axillary cymes; calyx-lobes, petals and stamens usually 4, sometimes more; ovary superior; style very short: fr. a berry-like drupe, with 2-8 bony 1-seeded stones.— About 275 species in N. and S. Amer., Trop. and Temp. Asia, and few in Afr., Austral, and Eu. Monograph by Loesener in Nov. Act. Leop.-Carol. Acad. 71, pt. 1 (1901).

The hollies have medium-sized, simple leaves, small, inconspicuous, whitish flowers in axillary clusters or solitary, and black, red or sometimes yellow berries, remaining on the branches often until the following spring. Of the evergreen species, only I. glabra and I. opaca are hardy North, and also I. crenata in somewhat sheltered positions. I. aquifolium, I. pernyi, and 7. cornuta are more tender, but stand many degrees of frost if sheltered, while most of the others can be grown only in the South. Of the deciduous species, I. decidua, I. monticola, I. laevigata and 7. I. verticillata are hardy North; also I. serrata and some other Japanese species are hardy or nearly so. The hollies, especially those with scarlet or red berries, are highly ornamental, and the berried branches of I. opaca and I. aquifolium are in great demand for Christmas decoration. Also I. laevigata and I. verticillata, the prettiest in fruit of the deciduous kinds, are sometimes sold for this purpose. The deciduous species are mostly shrubs, while many of the evergreen species grow into small or medium-sized trees, and I. opaca is the tallest of the broad-leaved evergreens which are hardy North and thrives even on extremely poor soil, and has good color also; the evergreens I. crenata, and I. glabra always remain shrubby. I. aquifolium is a favorite evergreen in English gardens, and numerous varieties are there in cultivation; it also grows well on the Pacific coast from British Columbia to California. It stands severe pruning well, and can be clipped and trained into almost every shape; it also makes fine hedges, but its slow growth is a disadvantage. As the chief value of the deciduous species is in the ornamental fruits, and the hollies are dioecious, care should be taken to choose in planting mostly pistillate plants and a few staminate ones and to give the former the most prominent place. The light, close-grained and tough wood of some of the arborescent species is much valued for turnery-work, engraving and cabinent-making. The leaves of some tropical species, as I. paraguariensis and 7. conocarpa, yield a kind of tea known as Yerba de Mate, or Paraguay tea, which is much used in South America. The hollies grow best in rich, well-drained soil, and the evergreen ones in partly shaded situations, but I. laevigata, I. verticillata and also I. serrata prefer moist places, and grow even in swamps. Most of the species grow slowly, and are not easily transplanted when older. The best tune for moving the evergreen species is the early fall, when the young wood has almost ripened, or in the spring just before the plants start into new growth. The leaves should be stripped on I. opaca and I. aquifolium when transplanted, particularly if at all exposed—or at least nearly all. This is absolutely necessary to insure success. Wild hollies may be handled this way with success, particularly if cut back as well. Propagation is by seeds, which do not germinate until the second year, and are therefore stratified and treated like those of the slow-growing hawthorns. The young seedlings should be transplanted^ after the second year. The evergreen species may be" increased by cuttings of ripened wood under glass, especially the shrubby ones; they are also sometimes grafted or budded on seedlings of I. aquifolium or I. opaca.

'''Holly''' ('''''Ilex''''') is a genus of about 400 species of [[flowering plant]]s in the family [[Aquifoliaceae]], and the only genus in that family. They are [[shrub]]s and [[tree]]s from 2-25 m tall, with a wide distribution in [[Asia]], [[Europe]], north [[Africa]], and [[North America|North]] and [[South America]]. The [[leaf|leaves]] are simple, and can be either [[deciduous]] or [[evergreen]] depending on the species, and may be entire, finely toothed, or with widely-spaced, spine-tipped serrations. Hollies are mostly [[Plant sexuality|dioecious]], with male and female [[flower]]s on different plants, with some exceptions. [[Pollination]] is mainly by [[bee]]s and other [[insect]]s. The [[fruit]] is a small [[berry]], usually red when mature, with one to ten seeds.

Holly berries are mildly toxic and will cause vomiting and/or diarrhea when ingested by [[human|people]]. However they are extremely important food for numerous species of [[bird]]s, and also are eaten by other wild animals. In the fall and early winter the berries are hard and apparently unpalatable. After being frozen or frosted several times, the berries soften, and become edible. During winter [[storm]]s, [[bird]]s often take refuge in hollies, which provide [[shelter]], protection from [[predator]]s (by the spiny leaves), and [[food]]. The flowers are sometimes eaten by the [[larva]] of the [[Double-striped Pug]] [[moth]]. Other [[Lepidoptera]] whose larvae feed on holly include ''[[Bucculatricidae|Bucculatrix ilecella]]'' (which feeds exclusively on holly) and the [[Engrailed]].

  −
The species ''Ilex mucronata'', formerly treated in a separate genus ''Nemopanthus'', is now included in ''Ilex'' on molecular data (Powell et al. 2000).

===Origin of Name===
  −
  −
  −
The origin of the word holly is the [[11th century|11<sup>th</sup> century]] [[Old High German]] ''hulis'' and [[Old English]] ''holegn'' both meaning holly. The word ''hulis'' originates from an even older proto-Germanic word ''khuli'' - a shortened derivation of the ancient [[Gaelic language|Gaelic]] ''cuilieann'' both meaning holly. Today in modern Gaelic, holly is  still known as ''cuileann''.
     −
The botanic name ''ilex'' was the original Latin name for the [[Holm oak]], which has similar foliage to common holly, and is occasionally confused with it.

In many western cultures, holly is a traditional [[Christmas]] decoration, used especially in [[wreath]]s. Many of the hollies are highly decorative, and are widely used as ornamental plants in [[garden]]s and [[park]]s. The [[wood]] is heavy, hard and white; one traditional use is for [[chess]] pieces, with holly for the white pieces, and [[ebony]] for the black. Other uses include turnery, inlay work and as firewood. [[Loom]]s in the [[1800s]] used holly for the spinning rod. Because holly is dense and can be sanded very smooth, the rod was less likely than other woods to snag threads being used to make cloth.

Several [[Americas|American]] holly species are used to make various [[caffeine]] rich teas. The [[South America|South American]] ''I. paraguariensis'' is used to make [[yerba mate]], a common drink. ''[[Ilex guayusa|I. guayusa]]'' is used both as a stimulant and as an admixture to the [[entheogen]]ic tea [[ayahuasca]]; The leaves of ''I. guayusa'' have the highest caffeine content of any known plant. In [[North America|North]] and [[Central America]], ''[[Ilex vomitoria|I. vomitoria]]'', [[Yaupon holly|Yaupon]], was used by southeastern [[Native_Americans_in_the_United_States|American Indians]] as a ceremonial stimulant and emetic known as the [[black drink]].  As the name suggests, the tea's purgative properties were one of its main uses, most often ritually. In [[China]], the young leaf buds of ''[[Ilex kudingcha| I. kudingcha]]'' are processed in a method similar to [[green tea]] to make a [[tisane]] called [[Ku Ding tea]].
