2: Edible fruits and nuts

Castanea sativa Miller

FAGACEAE

European chestnut, Spanish chestnut (En). Marronnier, châtaignier (Fr).

Originating from the Mediterranean, now cultivated in mild temperate Europe and subtropical regions. Occasionally planted in United States, Soviet Union, and in mountain areas of the tropics, e.g. in Indonesia at 1400 m altitude.

The nuts are eaten raw, roasted or dried, or prepared into chocolates, pastries, etc. The bark contains tannin. Trees are also planted as ornamentals or to protect against erosion.

Tree, up to 30 m tall. Leaves oblong-lanceolate, up to 22 cm long, coarsely serrate. Fruit a spiny 2—4-valved burl (cupule), containing 1—4 nuts. Nuts flattened to subglobose, 1—3 cm diameter, brown. Many cultivars exist. Other Castanea species with edible nuts might be worth trying in the higher altitude tropics, e.g. Castanea dentata Borkh. (American chestnut), Castanea mollissima Blume (Chinese chestnut), Castanea crenata Sieb. & Zucc. (Japanese chestnut), Castanea pumila (L.) P. Miller (dwarf chestnut).
