1. A weed that grows among wheat and other grain; alleged by modern naturalists to be the lolium temulentum, or darnel. Didst not thou sow good seed in thy field? From whence then hath it tares? (Matt. Xiii. 27) The darnel is said to be the tares of Scripture, and is the only deleterious species belonging to the whole order. (Baird)
