A maritime plant that is common on the sandy coast line. It occurs, however, at two to four miles from the sea on banks and roadsides near Bryansford and Castlewellan. E. moschatum (Linn.), Le Herit. Roadside a half mile north of Annalong; not seen by us at Kilkeel, and the note in Irish Flora "abundant at Kilkeel Bay" probably refers to the preceding species. E. maritimum, Le Herit.

[We have thought it best to keep the two latter forms, for the present, under R. macrophyllus, though Prof. Babington's present view (in litt.) is that umbrosus and glabratus, together with R. maassii, Focke, might be combined as an aggregate under R. nemoralis, Müll.] Var. schlectendalii W. & N. Moygannon Glen. Though R. macrophyllus has only been positively identified from the above limited number of localities, yet this in its various forms is one of the commonest brambles of the district.
