Etymology: "Unifoliate" is a plain botanical compound, built from two Latin-derived English parts. The first, "uni-", comes from Latin "ūnus," meaning "one," which in turn descends from an ancient root shared with many Indo-European words for the number one. The second part, "foliate," comes from Latin "foliatus," meaning "leafed" or "furnished with leaves," itself formed from "folium," "leaf." Putting the two together gives the literal sense "one-leaved," and botanists use it to describe plants such as certain citrus species or trifoliate-type plants whose stems or branches carry just a single leaf. The construction follows the same pattern as older English botanical terms like "trifoliate," with "uni-" simply replacing "tri-" (three) to count the leaflets.
