"According to Guppy the type of Mucuna seed that is most frequently gathered on the beaches of Western Europe is that provisionally referred by him to Mucuna "near urens" and since suggested to be Mucuna altissimo. A drift seed of this was picked up by Guppy on the beach at Salcombe in Devon. In this the seeds are described as slightly flatter or more depressed than in M. urens and rather over and inch in diameter. They possess a narrower but a similarly encircling raphe. In color they are usually of a dark brown and when of a lighter hue they display black mottlings. Another drift seed, found at St. Helens in the Isle of Wight, is in the Kew Museum. Similar seeds have occurred in the Faroe and the Shetland Islands."
