Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Naturalised

Robust caespitose perennial. Culms erect, to 1 m high or more. Leaves prominently veined, glabrous or with scattered hairs; blades flat or loosely inrolled, sharp-pointed, to 50 cm long, 2–6 mm wide, scabrous toward the tip, otherwise smooth; ligule truncate, minutely ciliate, c. 0.5 mm long; auricles hardly developed. Inflorescence a distichous spike, 10–40 cm long. Spikelets 10–25 mm long, often curving away from the rachis in the upper part; glumes truncate, 7–11 mm long, the upper longer than the lower by up to 3 mm, both prominently 5–11-nerved, sometimes weakly scabrous along midrib; lemma obtuse or notched at apex, 9–13 mm long, c. 5-nerved, only the midrib prominent, glabrous except for finely ciliate margins; palea slightly shorter than lemma. Flowers Nov.–Mar.

*CVU, *DunT, *GipP, *Gold, *MuF, *MuM, *OtP, *VRiv, *VVP, *WaP, *Wim. Planted as a crop mostly on heavier soils, sometimes prone to inundation or salination, but spreading from cultivation in many areas and now recognised as an aggressive invader of grasslands.

The cultivar, 'Tyrell', is often selected for salted land.

Often treated as Lophopyrum (or Thinopyrum) elongatum but that species is a low-growing, selfing diploid whereas L. ponticum is a tall, out-crossing decaploid.

Should Lophopyrum be included in Thinopyrum as some authors maintain (e.g. Barkworth et al. 1983) ,there is no current valid name for L. ponticum in Thinopyrum.
