North American J. microcarpa and J. major, and J. cinerea most closely related to several e. Asian species.

WEAKLEY FLORA

SCIENTIFIC NAME: Juglans nigra
COMMON NAME: Black Walnut
SYNONYMY: [= C, F, FNA, G, K1, K3, Mo, Pa, RAB, Va, W, WH3, WV; = Wallia nigra (Linnaeus) Alefeld - S]
PHENOLOGY: Apr; Oct.
HABITAT: Moist, nutrient-rich forests of floodplains and slopes, calcareous hammocks.
COMMENTS: MA west to MN, south to Panhandle FL and TX. The dark brown wood is famous for cabinetry and other uses; it is one of the most prized of North American hardwoods. The nuts, though difficult to crack, are prized for their intense flavor. The husk is used as a dye. Country people dehusk the nuts by putting them in dirt or gravel driveways where the passage of car tires removes the husk but does not crack the nut.
