Carya (Karya, Greek name for the walnut tree). Syn., Hicoria. Juglandaceae. Hickory. Trees grown for their handsome foliage and strong habit, and some species for their edible nuts.

Deciduous: branches with solid pith: lvs. alternate, without stipules, with 3-17 serrate lfts.: fls. monoecious, apetalous, appearing with the lvs.; stami nate fls. in axillary, slender, pendulous catkins, each fl. with 3-10 stamens, borne in the axil of a 3-lobed bract; pistillate fls. in a terminal, 2-10-fld. cluster or spike, consisting of a 1-celled ovary inclosed by a 4- lobed involucre: fr. globular to oblong, with a husk separating into 4 valves and a bony nut, incompletely 2-4-celled.—About 18 species of hickory, all in E. N. Amer. from Canada to Mex.; the Chinese species recently described by Dode from nuts only is probably not a Carya. See Rep. Mo. Bot. Gard. 7, pp. 28-42, pls. 1-23, and Rep. of U. S. Dept. Agric., Div. Pomol., Nut-Culture (1896), cited below as U. S. N. C. (the first number referring to the plate, the second and third to the figure). Hicoria is actually the older name, but Carya is retained as one of the "nomina conservanda" of the Vienna code of nomenclature, because of its long-established usage.

The hickories are hardy ornamental; usually tall trees with rather large, deciduous odd-pinnate leaves, small greenish flowers, the staminate ones in conspicuous pendulous racemes, and with rather large green dehiscent fruits inclosing a mostly edible nut. The hickories are among the most beautiful and most useful trees of the American forest, and are all very ornamental park trees, with a straight, sometimes high and slender trunk and a large, graceful, pyramidal or oblong head of usually light green foliage, turning from yellow to orange or orange-brown in fall. They are hardy North except C. Pecan, C. aquatica and C. myristicaeformis, but C. Pecan thrives rarely in Massachusetts in sheltered positions. Most of the species have heavy hard strong and tough wood, much valued for many purposes, especially for handles of tools, manufacture of carriages and wagons, also for making baskets and for fuel. The nuts of some species, as C. Pecan and C. ovata, also C. laciniosa and some varieties of C. glabra and C. alba, are edible, and are sold in large quantities, mostly gathered from the woods, though in later years orchards of improved varieties have been planted. The hickories generally thrive best in rich moist soil, but some, especially C. glabra, C. alba and C. ovata, grow equally well in drier localities. They are of rather slow growth, and difficult to transplant if taken from the woods; therefore the seeds are often planted where the trees are to stand, but if grown in the nursery and transplanted several times when young, trees 6-10 ft. high may be transplanted successfully.

Propagation

Propagation is usually by seeds stratified and sown in spring in rows about 3 inches deep; named varieties may be grafted in spring in the greenhouse, on potted stock of C. cordiformis, which seems to be the best species for this purpose, veneer- or splice-grafting being usually employed; sometimes also increased by root-sprouts. For further horticultural advice, see Hickory-nut and Pecan.CH

Pests and diseases

A large number of insects prey upon the hickory, attacking the wood, foliage and fruit, for which see the Fifth Ann. Rep. of the U. S. Entom. Com., pp. 285-329. There are also some fungi sometimes causing an early defoliation of the trees.CH
