Archaic term for wheat; replaced by 小麦 (こむぎ) in modern Japanese. May appear in historical texts or poetry.
See also: 小麦
The notation '真麦' can be found in old documents.
The historical derivation is uncertain; the kanji 真 (true) and 麦 (wheat) may have been used to distinguish it from other grains, but this is speculative.
