Species Description

Stace 4:

Leymus arenarius (L) Hochst. (Elymus arenarius L.) - Lyme-grass.

Culms to 1.5(2)m, very glaucous; leaves flat, becoming inrolled, 8-20mm wide; spike ≤35cm, dense; spikelets 20-32mm, overlapping; 2n=56. Native; mobile sand on maritime dunes, rarely casual or naturalised inland; frequent round coasts of most of British Isles, but absent from large parts of South England and South & West Ireland and from Channel Islands. Culms are highly susceptible to the fungal smut Ustilago hypodytes (Schltdl.) Fr., which often causes deformation and abortion of all the inflorescences.
