The genus includes 17-19 species of [[deciduous]] trees with pinnately compound [[leaf|leaves]] and large [[nut (fruit)|nuts]]. A dozen or so species are native to [[North America]] (11–12 in the [[United States]], 1 in [[Mexico]]), and 5–6 species from [[China]] and [[Indochina]]. Another Asian species, Beaked Hickory, previously listed as ''Carya sinensis'', is now treated in a separate genus ''[[Annamocarya]]'', as ''Annamocarya sinensis''. Hickory [[flower]]s are small yellow-green [[catkin]]s produced in spring. They are [[pollination|anemophilous]] and self-incompatible. The [[fruit]] is a globose or oval nut, 2–5 cm long and 1.5–3 cm diameter, enclosed in a four-valved husk which splits open at maturity. The nut shell is thick and bony in most species, thin in a few, notably ''C. illinoinensis''; it is divided into two halves which split apart when the seed germinates. ===Species and classification=== In the [[APG system]], genus ''Carya'' (and the whole [[Juglandaceae]] family) has been recently moved to the [[Fagales]] order. ;North America *'''''Carya'' sect.

These include: * [[Brown-tail]] (''Euproctis chrysorrhoea'') * the ''[[Coleophora]]'' case-bearers ''C. laticornella'' and ''C. ostryae''. * [[Regal moth]] (''Citheronia regalis''), whose caterpillars are known as hickory horn-devil * [[Walnut Sphinx]] (''Amorpha juglandis'') Another insect that uses the hickory tree as a food source is the [[hickory leaf stem gall phylloxera]] (''[[Phylloxera caryaecaulis]]''). [[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 of the phylloxera, or possibly because the galls are fleshy and tasty to the squirrels. [[Image:Pecans.jpg|left|thumb|200px|Nuts from the [[pecan]] trees are a popular food.]] ===Uses=== Hickory [[wood]] is extremely tough, yet flexible, and is valued for [[tool]] handles, [[bow (weapon)|bows]] (like [[taxus|yew]]), [[wheel]] spokes, [[cart]]s, [[drumstick]]s, [[Lacrosse]] stick handles, [[golf club (equipment)|golf club]] shafts (sometimes still called ''hickory stick'', even though made of steel or graphite), the bottom of skis, walking canes etc. and for punitive use as a [[switch (rod)|switch]] (like [[hazel]]), and especially as a cane-like [[caning#types and synonyms|hickory stick]] in schools. [[Baseball]] [[baseball bat|bats]] were formerly made of hickory but are now more commonly made of [[ash tree|ash]]. Hickory is also highly prized for [[wood-burning stove]]s, because of its high caloric content. Hickory wood is also a preferred type for smoke curing meats. In the Southern US, hickory is popular for cooking [[barbecue]], as hickory grows abundantly in the region, and adds flavor to the meat. Hickory is sometimes used for hardwood flooring due to its durability and character. A [[bark]] extract from shagbark hickory is also used in an edible syrup that is similar to [[maple syrup]], with a slightly bitter, smoky taste. The [[nut (fruit)|nut]]s of some species are palatable, while others are bitter and only suitable for animal feed. Shagbark and Shellbark Hickories, along with the [[Pecan]], are regarded by some as the finest nut trees. When cultivated for their nuts, note that because of their self-incompatibility, clonal (grafted) trees of the same [[cultivar]] cannot pollinate each other. Two or more cultivars must be planted together for successful [[pollination]]. Seedlings (grown from hickory nuts) will usually have sufficient genetic variation. == See also == * [[walnut]] (also used in waterskis) ==External links== *[http://www.cirrusimage.com/hickory.htm ''Carya''] Large-format diagnostic photos, [[Morton Arboretum]] acc. 29-U-10 *[http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=105766 Flora of North America: ''Carya''] *[http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=105766 Flora of China: ''Carya''] *[http://extension-horticulture.tamu.edu/carya/species/index.htm USDA Agricultural Research Service: ''Carya''] *[http://www.thenutfactory.com/kitchen/edible/facts-hickories.html Edibility of different species' nuts, from a snack food manufacturer] *[http://www.cas.vanderbilt.edu/bioimages/pages/compare-hickories.htm Comparison of eastern North American hickories at bioimages.vanderbilt.edu] *[http://www.cas.vanderbilt.edu/bioimages/pages/carya-fruits.htm Comparison of hickory nuts at bioimages.vanderbilt.edu] [[Category:Juglandaceae]] [[Category:Wood]] [[Category:Pollination]] [[Category:Edible nuts and seeds]] [[da:Hickory]] [[pdc:Hickernissbaam]] [[de:Hickory (Pflanze)]] [[es:Carya]] [[eo:Hikorio]] [[fr:Caryer]] [[it:Carya]] [[nl:Carya]] [[no:Hickory]] [[pl:Orzesznik]] [[pt:Carya]] [[ru:Гикори]] [[fi:Hikkorit]] [[sv:Hickorysläktet]]
