is a type of tree, comprising the genus Carya (Ancient Greek: κάρυον, káryon, meaning "nut"). The genus includes 17 to 19 species. Five or six species are native to China, Indochina, and India (State of Assam), as many as 12 are native to the United States, four are found in Mexico, and two to four are from Canada. Hickories are deciduous trees with pinnately compound leaves and large nuts. Hickory
flowers are small, yellow-green catkins produced in spring. They are wind-pollinated and self-incompatible. The fruit is a globose or oval nut, 2–5 cm (0.79–1.97 in) long and 1.5–3 cm (0.59–1.18 in) diameter, enclosed in a four-valved husk, which splits open at maturity. The nut shell is thick and bony in most species, and thin in a few, notably the pecan (C. illinoinensis); it is divided into two halves, which split apart when the seed germinates. Beaked hickory ( Annamocarya
sinensis) is a species formerly classified as Carya sinensis, but now adjudged in the monotypic genus Annamocarya.

Ecology[edit] Hickory
is used as a food plant by the larvae of some Lepidoptera species. These include:

Luna moth (Actias luna) Brown-tail
(Euproctis chrysorrhoea) Coleophora
case-bearers, C. laticornella and C. ostryae Regal moths (Citheronia regalis), whose caterpillars are known as hickory horn-devils Walnut sphinx
Walnut sphinx
(Amorpha juglandis) The Bride (nominate subspecies Catocala neogama
Catocala neogama
neogama) Hickory Tussock Moth
Hickory Tussock Moth
(Lophocampa caryae)

The hickory leaf stem gall phylloxera ( Phylloxera
caryaecaulis) also uses the hickory tree as a food source. Phylloxeridae are related to aphids and have a similarly complex life cycle. Eggs hatch in early spring and the galls quickly form around the developing insects. Phylloxera
galls may damage weakened or stressed hickories, but are generally harmless. Deformed leaves and twigs can rain down from the tree in the spring as squirrels break off infected tissue and eat the galls, possibly for the protein content or because the galls are fleshy and tasty to the squirrels. The pecan gall curculio (Conotrachelus elegans) is a true weevil species also found feeding on galls of the hickory leaf stem gall phylloxera. The banded hickory borer (Knulliana cincta) is also found on hickories. Fruit[edit] Some fruits are borderline and difficult to categorize. Hickory
nuts (Carya) and walnuts (Juglans) in the Juglandaceae
family grow within an outer husk; these fruits are sometimes considered to be drupes or drupaceous nuts, rather than true botanical nuts. "Tryma" is a specialized term for such nut-like drupes.[3][4] Uses[edit]

Finished hickory in a cabinet

wood is very hard, stiff, dense and shock resistant. There are woods that are stronger than hickory and woods that are harder, but the combination of strength, toughness, hardness, and stiffness found in hickory wood is not found in any other commercial wood.[5] It is used for tool handles, bows, wheel spokes, carts, drumsticks, lacrosse stick handles, golf club shafts (sometimes still called hickory stick, even though made of steel or graphite), the bottom of skis, walking sticks, and for punitive use as a switch (like hazel), and especially as a cane-like hickory stick in schools and use by parents. Paddles are often made from hickory. This property of hickory wood has left a trace in some Native American languages: in Ojibwe, hickory is called "mitigwaabaak", a compound of mitigwaab "bow" and the final -aakw "hardwood tree" [6] Baseball
bats were formerly made of hickory, but are now more commonly made of ash. Hickory
is replacing ash as the wood of choice for Scottish shinty sticks (also known as camans). Hickory
was extensively used for the construction of early aircraft. Hickory
is also highly prized for wood-burning stoves and chimineas because of its high energy content. Hickory
wood is also a preferred type for smoking cured meats. In the Southern United States, hickory is popular for cooking barbecue, as hickory grows abundantly in the region and adds flavor to the meat. Hickory
is sometimes used for wood flooring due to its durability in resisting wear and character. Hickory
wood is not noted for rot resistance. A bark extract from shagbark hickory is also used in an edible syrup similar to maple syrup, with a slightly bitter, smoky taste. The nuts of some species are palatable, while others are bitter and only suitable for animal feed. Shagbark and shellbark hickory, along with pecan, are regarded by some as the finest nut trees. When cultivated for their nuts, clonal (grafted) trees of the same cultivar cannot pollinate each other because of their self-incompatibility. Two or more cultivars must be planted together for successful pollination. Seedlings (grown from hickory nuts) will usually have sufficient genetic variation. Gallery[edit]
