The Irish ])lant, usually named A. Inpponica, has shorter branehes 
to its j)aniele than the Fhiglish and Seoteh plants, but that will 
not afford a eonstant eharaeter. Its longer and sharper ligule is

shai)e as those of A. stricta from which I am unable to distin- 
guish it. A. lapponica (Wahl.) has 1-nervcd glumes, a bent awn, 
and hairs as long as the pale. — Bogs. Formerly found near F’erfai-.
