GENUS INDEX

GENUS CODE: JUGLA
GENUS SCIENTIFIC: Juglans
GENUS AUTHORITY: L.
GENUS COMMON: Walnut
GENUS SUMMARY: A genus of about 21 species, trees and shrubs, of Mediterranean Europe to e. Asia, and North America to Andean South America. Stanford, Harden, & Parks (2000) present a molecular phylogeny and a discussion of biogeography; our two species are distantly related within the genus, with J. nigra most closely related to sw. 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.
