Hilary and I saw this today near Jersey Marine.
Significant features are the pale creamy-green flowers with obtuse perianth segments, the lax inflorescence, the hairy upper stem, and the rather narrow, channelled leaves which are not really whorled. It looks like a form of Epipactis muelleri (= Epipactis leptochila), but not the form normally known as Narrow-lipped Helleborine (E. muelleri Var. leptochila). It looks more like Var. dunensis to me, although it isn't a perfect fit. It wasn't growing in dunes. Comments appreciated.
