This unique, largely dioecious root-suckering shrub, with unusually light wood, is known from thin marshy woods and shores along rivers and sloughs on the Gulf Coastal Plain, with disjunct localitiesthat are mostly in se. Tex, n. Flo. and e. Ark. (K). It is documented as far north as se. Mo., but no colls. are known from Ky. or Tenn. According to an "old forester" from western Kentucky, "cork bush" used to grow on natural levees of the Mississippi River in FULT before the flood dikes were built (R. Athey, pers. comm. in 1983 to M). There is also an old unverified report from near Memphis, Tenn. (D. Estes, pers. comm.).
