What does ilex mean?
Ilex most commonly denotes a holly, especially the familiar evergreen shrub or tree with prickly leaves and red berries. It can also name the holm oak, Quercus ilex, an evergreen oak native to the Mediterranean region. The word is chiefly encountered in botanical contexts, formal writing, and descriptions of gardens or landscapes in which the dense, year-round foliage of ilex is significant. Although ordinary speakers usually say holly for the best-known members of the genus, ilex has a broader botanical application that includes several related species. The term also survives in the established name holm oak, where its older Latin source is reflected. In modern usage, capitalization and italics usually distinguish the genus name, Ilex, from the common noun; the older sense referring specifically to the holm oak remains valid but requires more context to avoid confusion with holly.

"Red berries brightened the ilex hedges after the first frost."
"The botanist identified the evergreen tree as a Mediterranean holm oak, also known as ilex."
The usual plural is ilexes, though the plural is rarely needed because the word is chiefly used in botanical or literary contexts.
"Several ilexes grew along the northern boundary."
The Latin name once referred to the holm oak before it became associated with the spiny evergreen we know as holly.

Where does ilex come from?
The word comes from Latin ilex, which originally denoted the holm oak. The Latin name was later applied to the holly genus because both the holm oak and holly are evergreen trees with a broadly similar appearance. The English form was adopted for botanical and literary use and is now principally associated with the genus Ilex.

How ilex is actually used
In botanical writing, the genus name is normally capitalized and italicized as Ilex. In general prose, ilex is relatively uncommon and may sound literary or formal; when it denotes the holm oak, the species name Quercus ilex provides greater precision.
