Etymology: Gnetophytes take their name from a genus of plants called Gnetum, which includes the tropical tree "gnemon" (Gnetum gnemon) found in Southeast Asia. The genus name likely comes from "gnemon," a Malay name for the tree, and Linnaeus adopted it as a scientific name. The tree's seeds are eaten in parts of Indonesia and the Philippines, so the name reaches back to local knowledge of the plant. The second half, "-phyte," comes from the Greek "phyton," meaning plant, from "phuein," to grow. It appears in many botanical terms, such as "epiphyte" (a plant growing on another plant) and "saprophyte" (a plant living on dead matter). The group that includes Gnetum also contains two other genera, Ephedra and Welwitschia, so the term covers plants that look quite different from one another. Gnetophyte is a modern scientific coinage built from these Greek and Malay roots, and it is not a word from ancient Greek.
