tares

from Easton's 1897 Bible Dictionary
Tares
the bearded darnel, mentioned only in Matt. 13:25-30. It is the
Lolium temulentum, a species of rye-grass, the seeds of which
are a strong soporific poison. It bears the closest resemblance
to wheat till the ear appears, and only then the difference is
discovered. It grows plentifully in Syria and Palestine.
