Etymology: "Laminariales" is the plural of "Laminaria," the Latin-style name of a genus of brown kelp. The genus name was created in 1813 by the French naturalist Jean Vincent Félix Lamouroux, who took the Latin "lamina," meaning a thin plate or blade, and added a suffix to describe the broad, flattened fronds these seaweeds grow. The order name follows the same logic: "-ales" is the standard ending for orders in botanical classification, so "Laminariales" groups together the kelps that share that blade-like form. The word is a modern scientific coinage, not an ancient one. Lamouroux and later taxonomists drew on classical Latin, but no Roman or Greek writer used "laminaria" for seaweed. The sense of "lamina" as a thin sheet goes back to Latin, where it referred to a plate of metal or a thin layer of wood or stone, and the botanical application simply borrowed that visual image for the kelp's flattened blades.
