Shrub, tree; monoecious.
Leaf: odd-(even-)1- pinnate, alternate, deciduous; stipules 0.
Inflorescence: catkin, generally appearing before leaves, 1 or clustered; flowers generally 1 in bract axils.
Staminate inflorescence: pendent, elongate, many-flowered, on last yr's twigs.
Pistillate inflorescence: erect; flowers 1–many, at tip of new twigs.
Staminate flower: calyx [0 or] lobes generally 4 [2, 6]; petals 0; stamens 3–40; pistil 0 or vestigial.
Pistillate flower: calyx  or lobes 4; petals 0; stamens 0; ovary 1, inferior, chamber 1 above, generally 2 below, styles 2, plumose.
Fruit: nut enclosed in husk or winged nutlets.
9 genera, > 60 species: n temperate, subtropical mountains; some ornamental, cultivated for wood, nuts (Carya hickory, pecan; Juglans walnut). [Stone 1997 FNANM 3:416–428] In Carya, Juglans, husk included in fruit diam, even though derived from involucre, calyx, and therefore not technically part of fruit. —Scientific Editor: Thomas J. Rosatti.

Key to Juglans
Stem: bark smooth to furrowed in age, gray to gray-brown; twig centers chambered; buds scaly.

Fruit: 1–3 unwinged nuts per inflorescence; leathery husk enclosing, not separating from each nut, not splitting.
21 species: North America, temperate Asia, South America. (Latin: Jove's nut) Wood used for interior finishing, furniture; source of nuts, dye. Juglans nigra L., occasionally planted, resembles Juglans hindsii but has leaflets uniformly pubescent abaxially, nuts deeply grooved, coarsely warty.
