Castanea seguinii, called Seguin chestnut, Seguin's chestnut, or Chinese chinquapin (a name it shares with Castanea henryi), and in Шаблон:Zh, mao li, is a species of chestnut native to southШаблон:Nbhcentral and southeast China.[1][2]

Description

Castanea seguinii are small trees or shrubs, rarely reaching 12Шаблон:Nbspm. Their stipules are narrowly lanceolate, 0.7 to 1.5Шаблон:Nbspcm long, and are shed (become deciduous) when the plant is in fruit. Leaf petioles are 0.5 to 1.5Шаблон:Nbspcm long. Leaves are 6 to 14Шаблон:Nbspcm long, with their abaxial sides covered with yellowishШаблон:Nbhbrown to gray scaly glands, and have sparse hairs along the veins when young. Leaf blades are oblongШаблон:Nbhobovate to ellipticШаблон:Nbhoblong in shape, with bases rounded or infrequently subcordate, but cuneate when young, with acuminate apices. Leaf margins are coarsely serrate. Male inflorescences are 5 to 12Шаблон:Nbspcm long and catkinШаблон:Nbhlike. Female inflorescences are held in a cupule, with one to two (rarely more) flowers in each. Cupules are 3 to 5Шаблон:Nbspcm wide, and covered with sparsely pilose spiny bracts which are 6 to 10Шаблон:Nbspmm long. Each cupule produces two or three nuts, rarely more, with each nut being 1.5 to 2.0Шаблон:Nbspcm in diameter.[2]

Ecology

Castanea seguinii grow in mixed mesophytic forests and thickets from 400 to 2000Шаблон:Nbspm in elevation.[2] Their bark is eaten by golden snubШаблон:Nbhnosed monkeys (Rhinopithecus roxellana) in winter.[3] In their native habitat they flower in May through July, and fruit from September to November.[2]

Uses

Its nuts are small, but are edible and occasionally cultivated or collected in the wild and consumed by locals.[2] Locals also practice coppicing for firewood.[4] Another use in China is as a trap crop for Dryocosmus kuriphilus gall wasps. By planting a hedge of C.Шаблон:Nbspseguinii around [[Castanea mollissima|C.Шаблон:Nbspmollissima]] (Chinese chestnut) orchards, the wasps will first encounter and attack the buds of the less valuable C. seguinii, allowing the galled twigs to be cut off and destroyed.[5]
