Juglandeae
An order of trees or shrubs with watery or resinous juice, natives, for the most part, of North America. Male flowers in catkins; perianth two, three, or six-parted, with a scaly bract; female flowers in terminal clusters, or in loose racemes, with distinct or united bracts; perianth adherent, three to five-parted. Fruit a dry drupe, with a strong and often two-valved endocarp; seed exalbuminous, two to four-lobed at the base. Leaves alternate, pinnate, stipulate. The wood of several of the species of Juglans is much prized by cabinet makers; and the bark of Juglans cinerea is used as a purgative in America. There are about five genera and thirty species. Illustrative genera are: Carya and Juglans.
