Nordic Bladderwort

Sarah and Fred Longrigg have looked at my bladderwort from Loch Ravag which was clearly Utricularia intermedia agg. and from a microscopic examination of the quadrifid hairs in the bladders have concluded that it is U. stygia (Nordic Bladderwort).  This is only the third record for the vice-county. and one of those is a little uncertain being a SNH Loch Survey record from Rum in 1993.
