What does milium mean?
Milium is an uncommon noun referring to a grass of the genus Milium, a small botanical group whose best-known members are wood millet and spring millet. These annual grasses have delicate branching flower clusters and occur in temperate regions, with some species favoring woodland or shaded habitats. The name also has a historical sense meaning millet or a grain of millet, reflecting the word’s origin in the Latin term for that cereal. Today, “Milium” appears chiefly in scientific, botanical, horticultural, and taxonomic contexts rather than everyday speech. It is therefore a useful word for readers interested in plant classification, grasses, or the history of crop cultivation. Because the genus name is conventionally capitalized and italicized in formal writing, capitalization distinguishes the modern taxonomic sense from the older historical sense for the grain itself.
Any grass of the genus Milium, a genus of annual grasses that includes wood millet and spring millet.
"The species Milium effusum is commonly known as wood millet."
Chiefly used in botanical and taxonomic contexts; the genus name is normally capitalized.
Historically, millet or a grain of millet.
"The remains of milium were found among the Roman settlement’s stored food."
A historical and literary use rather than a common modern term for the grain.
The inherited Latin plural is used when the word refers collectively to grains or historical units of millet; botanical writing generally avoids pluralizing the genus name and instead says “species of Milium.”
"Small quantities of milia were ground into meal."
Milium gives its name to a small but widespread genus of grasses, including the delicate wood millet often found in shaded meadows.

Where does milium come from?
The word comes from Latin milium, the ancient Roman term for millet, a grain also known today as a cereal grass. English acquired the word as a learned botanical and historical term, with the genus name Milium following modern taxonomic conventions. The related English word millet also ultimately derives from Latin milium through French, while miliary was formed from a Latin adjective connected with millet grain.
How milium is actually used
This is a rare and chiefly technical or historical term. In modern botanical usage, Milium is normally capitalized as a genus name; historical references to the grain use the lowercase noun.
