Carya spp.; hickory [Juglandaceae]  Moderate to large (to 100') deciduous trees with alternate, compound leaves in which the terminal leaflet is largest.  Staminate flowers are catkins, which are typically in clusters of 3.  Fruit is a nut whose husk splits when ripe.  Two species occur in Wisconsin.  C. ovata (shagbark hickory) is easily recognized by its characteristic bark and tends to grow on relatively dry sites in the southern half of the state.  C. cordiformis (bitter-nut hickory) is a tree of river terraces and moist woods and can be found somewhat farther north.  Hickory wood is strong and notably shock-resistant.  [085]
