Etymology: In Latin, "obversus" is the past participle of "obvertere," meaning "to turn toward" or "to turn against." The prefix "ob-" means "toward" or "against," and "vertere" means "to turn," so the literal sense is "turned to face." That physical image of something facing the viewer is the root of the botanical use. Botanists borrowed the Latin form to describe a leaf that is turned or set the reverse of its usual way, so that its normal upper and lower surfaces or its base and tip are inverted. English also took the same root for the face of a coin or medal, the side that faces the viewer, which is the sense most readers meet first. The botanical and numismatic uses share the same literal idea of a surface turned outward toward the observer.
