Boyd’s Bible Dictionary:
(stinking). A weed that grows among grain; doubtless the tare, identified as darnel (Job 31:40).
Concise Bible Dictionary:
Job asked that if he had done wickedly cockle might grow instead of barley; in the margin it reads “noisome weeds” (Job 31:40). Some suppose the darnel is alluded to, as in Matthew 13:25.
Darnel – Lolium Temulentum
