(Dios, Jove' s, pyros, grain; alluding to its edible fruit). Ebenaceae. Persimmon. Ebony. Woody plants grown partly for the handsome foliage and partly for their edible fruits; some species are valuable timber trees.

Deciduous or evergreen trees or shrubs, with alternate, rarely opposite, entire leaves, without stipules: flowers dioecious or polygamous in few- or many-flowered, axillary cymes, the pistillate often solitary, yellowish or whitish; calyx and corolla 3-7-, usually 4-lobed; stamens usually 8-16, included; styles 2-6; ovary 4 - 12-celled: fruit a large, juicy berry, 1-10-seeded, bearing usually the enlarged calyx at the base; seed flat, rather large. - About 190 species in the tropics, few in colder climates.

The few cultivated species are ornamental trees, with handsome lustrous foliage, rarely attacked by insects and with decorative and edible fruit. The only species which is tolerably hardy North is D. virginiana, while D. Kaki, much cultivated in Japan for its large edible fruits, is hardy only in the southern states. Most species have valuable hard and close-grained wood, and that of some tropical species is known as ebony. They thrive in almost any soil, but require, in cooler climates, sheltered and sunny positions. Propagated by seeds to be sown after maturity or stratified and sown in spring, and by cuttings of half-ripened wood or by layers; the tropical species by cuttings of mature wood in spring, with bottom heat; the fruit-bearing varieties are usually grafted or budded on seedling stock of D. virginiana.

A.G. 12:331-8, 459-462. - A very desirable and beautiful fruit-bearing tree for the southern states, where a number of different varieties introduced from Japan are cultivated, but the hardier varieties from the north of Japan and China, which are likely to be hardy north to New England, seem hitherto not to have been introduced Fig. 1273 is from Georgeson's articles in A. G. 1891. - The plant cult, in Eu. as D. chinensis, which is apparently the same as D. Roxburghii, differs from the Japanese forms of Kaki, which usually have elliptic and glabrescent leaves, in the narrower usually oblong leaves densely pubescent beneath, less so above, and in the greenish yellow subglobose fruit; it is tenderer than the common Kaki. It must not be confused with D. sinensis, Hemsl., an entirely different species from Cent. China, not in cultivation
