nearly to 250 yards. A plant found long ago by Sir John Trevelyan in Chartners Lough on the Wallington Moors, and thence transported to Wallington, appears to agree with the north European N. intermedium of Ledebour, a subspecies not known elsewhere in Britain. This is considered by Professor Caspary a hybrid between N. lutea and pumila, but it cannot possibly be so here.
