Etymology: Fucales is the scientific name for an order of brown seaweeds, the group that includes the wracks and bladderwracks found on rocky shores. The name comes from the Latin "fucus", which the Romans used for seaweed and also for a dye, and which the Greeks had borrowed in the form "phykos" for the same kind of algae. Botanists took the Latin word and gave it the ending "-ales", the standard suffix for orders in biological classification, so the name is a modern coinage built on an ancient word rather than something a Roman sailor would have recognised as a taxonomic label. The surprising twist is that "fucus" once named a red dye. The Romans used a purple-red colouring obtained from certain seaweeds, and the word covered both the plant and the colour, so the link between a shoreline plant and a pigment is older than any botanical classification. Early naturalists then applied the old name to the group of brown seaweeds that most resembled the Mediterranean wracks.
