Glumes 5-16 mm, (1/2) 2/3 as long as to somewhat exceeding the distal florets; lemmas 3.5-5.5 mm long, 1.2-1.8 mm wide, usually unawned, rarely awned, awns to 10 mm, attached 0.2-1 mm below the apices. Caryopses 3.2-4.5 mm long, 1.2-1.8 mm wide.

Discussion

Lolium temulentum subsp. remotum is native to Europe, Asia, and northern Africa. It originated as a weed in flax fields, through unintentional selection for seeds that could not be separated from flax seed using early harvesting techniques. It is a rare weed in the Flora region, being reported only from southern Ontario and California, where it grows in waste places and fields.
