Molinia caerulea subsp. arundinacea
Recent work by A.Atkinson has increased our knowledge of this subspecies of Purple Moor-grass in Cornwall. It has not yet proved possible to discriminate between the two subspecies, caerulea and arundinacea as regards habitat, but surveys are to continue both with this aim in mind and to see how far the characters of each overlap, (Stace, 1997 and Sell & Murrell, 1996).
