Etymology: Quercifolius is a Latinate botanical adjective built from "quercus", the Latin word for oak, and "folius", from "folium", leaf, so it literally means "oak-leaved". Botanists used this kind of descriptive Latin for plant names long after Latin had stopped being the everyday language of learning, and it appears as an epithet in plant and animal names, most famously in the oakleaf hydrangea, Hydrangea quercifolia. The "quercus" half is the older of the two, and its own history is not especially surprising. Its ancestors in the Italic languages are the source of the Latin word, and the same root gives English nothing directly, since English "oak" comes from a separate Germanic word. The pairing of the two Latin stems is a deliberate modern construction, a product of scientific naming rather than of ordinary speech.
