Hickory is a common name for

Indochina, and India (Assam), as many as twelve are native to the United States, four are found in Mexico, and two to four are native to Canada.[4][5]
A number of hickory species are used for their edible nuts, lumber or other wood and woodcraft products .

Hickories are

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
.

Etymology

The name "hickory" derives from a

Ancient Greek: κάρυον, káryon, meaning "nut
".

Ecology

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

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.

Evolutionary history

The oldest fossils attributed to Carya are Cretaceous pollen grains from Mexico and New Mexico. Fossil and molecular data suggest the genus Carya may have diversified during the Miocene.[9] Modern Carya first appear in Oligocene strata 34 million years ago. Recent discoveries of Carya fruit fossils further support the hypothesis that the genus has long been a member of Eastern North American landscapes, however its range has contracted and Carya is no longer extant west of the Rocky Mountains.[10][11]

Fossils of early

Pleistocene Ice Age beginning 2 million years ago obliterated it from Europe.[12] In Anatolia, the genus appears to have disappeared only in the early Holocene, probably related to human disturbance.[13] The distribution of Carya in North America also contracted and it completely disappeared from the continent west of the Rocky Mountains. Since fossil records show North America as having the largest number of Juglandaceae species, it is likely that the genus originated there and later spread to Europe and Asia.[citation needed

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.[16][17]

Nutrition

Uses

Finished hickory in a cabinet

Hickory

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".[19] Due to its grain structure, hickory is more susceptible to moisture absorption than other species of wood, and is therefore more prone to shrinkage, warping or swelling with changes in humidity.[20]

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

chimineas, as its density and high energy content make it an efficient fuel.[21] 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 and character.

soapmaking.[24]

The nuts of some species are palatable and were used by Cherokee Indians in making Kanuchi soup, 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. Pecans are the most important nut tree native to North America.[4]

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.
