Natural History

The Acadians of south Louisiana called all oaks "chene" which is the old French name for that genus. The Acadian French name for an acorn is "gland" and the wood is called "cheniere" (Holmes 1990). The name "cheniere" is also used to refer old beach remnants in the coastal marsh where live oaks grow. Blue jack oaks are found in sandy uplands of Louisiana, east and central Texas.
