Knowra Juglandaceae Juglandaceae Juglandaceae is a family of flowering trees and shrubs that includes walnuts, hickories, and pecans. Its members typically bear aromatic leaves and fruits enclosed in husks.
Juglans : A genus of trees that includes walnuts and produces fruits with a hard, ridged shell inside a husk. This genus supplies the family’s best-known edible nuts and its scientific name.
Wind pollination : The transfer of pollen between flowers by air currents. Many family members rely on wind rather than animal visitors to deliver pollen.
Walnut : An edible nut produced by trees in the genus Juglans. Walnuts are a major food crop within the family.
Fagales : An order of flowering plants that includes beech, birch, oak, and walnut families. Juglandaceae is one of the major tree families within this order.
Juglone : A naturally occurring naphthoquinone produced by some walnut trees, especially Juglans nigra. This compound underlies walnut-associated effects on some neighboring plants.
Carya : A genus of deciduous trees that includes hickories and pecans. Its species represent the family’s other major group of nut-producing trees.
Monoecy : A reproductive condition in which one plant bears separate male and female flowers. Walnuts and hickories commonly separate the sexes into different flowers on one tree.
Pecan : An edible nut produced by Carya illinoinensis, a tree native to North America. Pecan cultivation is one of the family’s most valuable agricultural uses.
Angiosperm : A flowering plant that develops seeds enclosed within an ovary, usually forming a fruit. Juglandaceae belongs to the flowering plants, whose defining trait is enclosed seeds.
Food forest : A deliberately designed planting that combines useful trees, shrubs, and other crops in layered vegetation. Walnuts and other family members can serve as canopy trees in perennial food systems.
