Carya pallida, sand hickory, or pale hickory is a species of hickory native to the southeastern United States. [6] It is a perennial, dicotyledonous plant which prefers rocky or sandy habitats. [7] The sand hickory can reach heights of up to 30m, but its typical height is between 9-24m. [8] [9] In an open area, Carya crowns are usually towering and slim. [10] The sand hickory nut is edible and consumed by various organisms. [7]

Description

Sand hickory bark changes appearance at maturity. [11] Young tree bark is even and a light-gray or brown colour. [10] Deep squamous ridges and dark-gray colours are present on the bark of older specimens. [12] Male catkins and female flowers grow on each plant making it monoecious. [12]

Carya pallida leaves are compound and alternate. [12] Leaflets are commonly ovate, and are in groups of 5 to 9, but 7 is most typical. Its rachis and midrib are hirsute with tattered, soft hairs. [11] The abaxial side is covered in scales ranging from silvery-blue to silvery-yellow. [11] Characteristic of hickory, C. pallida wood is thick, durable, and shock absorbent. Compared to other hickories, their twigs are slimmer. [8] Emerging buds are protected by mahogany bud scales. [11] Carya spp., the "true hickories", form extensive taproots which can make transplanting trees difficult or impossible. [13] [10] Loss of new trees is common, so extra care must be taken. [10] Carya pallida has the potential to be a fitting shade or specimen tree. [14]

Male catkins are 7 to 10 cm (3–4 in) long while female flowers are of similar size. Pollination occurs by wind dispersal. [11] Blooming occurs during the spring season from March to May. [15] Flowers range from yellow to green to brown. The nut of C. pallida is oval, dark-brown, and protected by a thin shell. [16] The kernel has been described as sweet tasting. [16] Kernels are consumed by rodents, squirrels, and large birds. [7]

Taxonomy

Carya pallida was first described in 1902 by botanist William W. Ashe in The Botanical Gazette in 1918. [17] [18] Synonyms include Hicoria pallida and Hicorius pallida. The common name of C. pallida, pale hickory, refers to the fair abaxial colour of the leaflet. [19] The common name, sand hickory relates to its abundance in sandy soils. [9] Some sources list a common name of pignut hickory, but this usually refers to Carya glabra. [19]

Carya pallida var. apposita, C. pallida var. arenicola, and C. pallida var. pyriformus are all varieties described by Ashe in the Bulletin of the Charleston Museum in 1918. [20]

Distribution and habitat

The sand hickory has been recorded in most southeastern states. [6] Its range extends from Delaware and to the west of Missouri. Carya pallida has not been recorded in Pennsylvania, West Virginia, or Ohio. Rarely, it can be found in southwestern Indiana, and it is uncommon in Maryland. [21] Population decline has been reported in Arkansas, Illinois, Indiana, Louisiana, and Missouri. [7] Sand hickory is also prominent in dry oak-hickory forests. [9] Specifically, it can be often found alongside longleaf pine (Pinus palustris) and scrub oak (Quercus marilandica). [8] [22] Hybridization with pignut hickory (Carya glabra) has been reported. [23]

Ethnobotany

Hickory wood is prized for its durability and utility. However, it requires additional manufacturing time due to its density. [24] Hickory wood is used for flooring, cooking, cabinetry, furniture, firewood, musical instruments, and tool handles. [24] Historically, golf club handles were crafted from hickory. [10] Economically, hickory wood is important to forestry landowners and industry. [24]

Notable specimens

A champion sand hickory was discovered in Greenville, SC, in 2015. It was recorded by the American Forests organization, and it is on the National Register of Champion Trees. It was 46m in height, and its crown spread 24m wide. As of 2020, this is the largest known sand hickory. [25]

Pathology

Carya pallida is a host plant of Microstroma juglandis. [26] This causes the fungal disease Downy Leaf Spot. Symptoms include fading light-green blots on the adaxial side and floury, white, furry blots on the abaxial side. Other hickory pathologies include Fusarium solani, Ceratocystis smalley, hickory bark beetles (Scolytus quadrispinosus), and flat-headed wood borers (Chalcophora japonica). [27]

Horticulture science

Carya spp. are more likely to contain rare earth elements (REE) or metallomes in their cells than other genera. [28] They have been found to contain Scandium, Lanthanum, Gadolinium, and other minerals. Currently, the role of the REE is unknown. Horticulturists speculate that they could aid in disease resistance, enzyme activities, ion transportation or other chemical functions. [28]

Carya pallida is a tetraploid species along with C. floridana, C. glabra, C. texana, and C. tomentosa. Carya spp. may be divided into three groups: 16, 24, and 32-chromosomal counts. [29]

<i>Carya laciniosa</i> Species of tree

Carya laciniosa, the shellbark hickory, in the Juglandaceae or walnut family is also called kingnut, big, bottom, thick, or western shellbark, attesting to some of its characteristics. It is a slow-growing, long-lived tree, hard to transplant because of its long taproot, and subject to insect damage. The nuts, largest of all hickory nuts, are sweet and edible. Wildlife and people harvest most of them; those remaining produce seedling trees readily. The wood is hard, heavy, strong, and very flexible, making it a favored wood for tool handles. A specimen tree has been reported in Missouri with 117 cm (46 in) diameter at breast height, 36.9 m tall, and a spread of 22.6 m.

<i>Carya tomentosa</i> Species of hickory tree

Carya tomentosa, commonly known as mockernut hickory, mockernut, white hickory, whiteheart hickory, hognut, bullnut, is a species of tree in the walnut family Juglandaceae. The most abundant of the hickories, and common in the eastern half of the United States, it is long lived, sometimes reaching the age of 500 years. A straight-growing hickory, a high percentage of its wood is used for products where strength, hardness, and flexibility are needed. The wood makes excellent fuel wood, as well. The leaves turn yellow in Autumn.

<i>Carya myristiciformis</i> Species of tree

Carya myristiciformis, the nutmeg hickory, a tree of the Juglandaceae or walnut family, also called swamp hickory or bitter water hickory, is found as small, possibly relict populations across the Southern United States and in northern Mexico on rich moist soils of higher bottom lands and stream banks. Little is known of the growth rate of nutmeg hickory. Logs and lumber are sold mixed with other hickories. The nuts are an oil-rich food for wildlife.

<i>Carya ovalis</i> Species of tree

Carya ovalis, the red hickory or sweet pignut hickory, is a fairly uncommon but widespread hickory native to eastern North America. It is typically found growing in dry, well drained sandy upland ridges and sloped woodlands from southern Ontario, Canada, and in the United States east to New Hampshire, south to northern Florida west to eastern Texas and north-west to Nebraska. This species was formerly treated as a variety or northern ecotype of the pignut hickory C. glabra, described as Carya glabra var. odorata. This discrepancy has not yet been completely resolved, and some sources and authors still consider red hickory as a variety or synonym of pignut hickory. However both trees are quite morphologically distinct.

Oak–hickory forest is a type of North American forest ecosystem, and an ecoregion of the Temperate broadleaf and mixed forests Biome.
