Castanea pumila
Also called Chinquapin, Allegheny chinquapin, Allegheny Chinkapin, Dwarf Chestnut, Golden Chinquapin, Allegeny Chinkapin, American Chinquapin
Allegheny chinquapin is a spreading shrub or small tree native to the southeastern United States, known for its edible nuts and relative resistance to chestnut blight. It grows best in well-drained, sandy or rocky soil in full sun or partial shade.
Castanea pumila, commonly known as the Allegheny chinquapin, American chinquapin (from the Powhatan) or dwarf chestnut, is a species of chestnut native to the southeastern United States. The native range is from Massachusetts and New York to Maryland and extreme southern New Jersey and southeast Pennsylvania south to central Florida, west to eastern Texas, and north to southern Missouri and Kentucky. The plant's habitat is dry sandy and rocky uplands and ridges mixed with oak and hickory to 1000 m elevation. It grows best on well-drained soils in full sun or partial shade. Allegheny chinquapin is relatively resistant to chestnut blight compared to the closely-related American chestnut.
Allegheny chinquapin occurs in a variety of forest types and woodlands, including dry pinelands, old fields, pine plantations, and well-drained stream terraces. Allegheny chinquapin is closely related to the American chestnut, Castanea dentata, and both trees can be found in the same habitat. Allegheny chinquapin can be distinguished by its smaller nut (half the size of a chestnut) that is not flattened (chestnuts are flattened on one side). The leaves of the Allegheny chinquapin are smaller than the American chestnut and have less distinct teeth. Allegheny chinquapin, however, is less susceptible to the chestnut blight fungus that devastated the American chestnut. While the chinquapin does blight to some degree, it continues to send out suckers that will produce fruit. Chinquapins are quite vulnerable nevertheless, and there are many reports of heavily diseased and cankered trees.
John Smith of Jamestown made the first written record of the tree and its nuts in 1612, observing its use by the Native Americans. Native Americans made an infusion of chinquapin leaves to relieve headaches and fevers. The bark, leaves, wood, and seed husks of the plant contain tannin. The nuts can be blanched, dried, and rehydrated to be prepared as food. The wood is hard and durable and is sometimes used in fences and fuel, but the plant is too small for the wood to be of commercial importance.
