In Scottish heraldry, the Fraser coat-of-arms has three strawberry flowers on blue; McDonald and related ones have one ship on green. Fraser in Gaelic is Frisealach, which can be interpreted as 'men of the forest'. The verse, traditionally known as 'the magic verse', is equally traditionally associated with the battle in July 1544 called Blar na Leine, between Frasers of Lovat, with some McDonalds, and other McDonalds and some Camerons. So ye ken the noo!
