Species of tree

Myrica rubra, also called yangmei (; Cantonese: yeung4 mui4; Shanghainese: ), yamamomo (ヤマモモ), Chinese bayberry, red bayberry, yumberry, waxberry, or Chinese strawberry (and often mistranslated from Chinese as arbutus) is a subtropical tree grown for its fruit.

Myrica rubra is an evergreen tree that grows to a height of up to high, with smooth gray bark and a uniform spherical to hemispherical crown. Leaves are leathery, bare, elliptic obovate to oval lanceolate in shape, wedge shaped at the base and rounded to pointed or tapered at the apex, margin is serrated or serrated in the upper half, with a length of and a width of Leaves are alternately arranged on the branches are divided into petiole and leaf blade. The petiole is long. The leaf underside is pale green and sparsely to moderately golden glandular, the top surface is dark green. The species is dioecious. Male flowers with simple or unobtrusively branched bracts, are held in inflorescences individually or occasionally in groups of a few inflorescences in the leaf axils. Female flowers are long, in inflorescences with bare stems, the bracts almost circular with a diameter of about 1 millimeter, and have golden glands on the underside. The male flowers are accompanied by two to four egg shaped, sparse lanceolate leaves. Each male flower contains four to six stamens with dark red, elliptical anthers. Female inflorescences are single with multi flowered spikes of in length standing in the leaf axils. The rhachis is hairy and glandular. The cover sheets overlap, are hairless and only unobtrusively glandular. Female flowers are accompanied by four leaves. The upper ovary is velvety hairy, with a stylus with a two lobed scar. There are two slender scar lobes that are colored bright red. The flowering period extends from March to April in China, with fruits developing from May to June. The fruit is spherical, typically in diameter, with diameters up to 3 centimeters, a knobby surface. The surface is a thick skinned, typically a crimson red, but may vary from white to purple, with similar or somewhat lighter flesh color. At the center is a single seed, with a diameter about half that of the whole fruit. The flesh is sweet and very tart.

The plant was first described by João de Loureiro in Flora Cochinchinensis, 2, page 548 in 1790 under the name (basionym) Morella rubra The species was moved to the genus Myrica as Myrica rubra by Philipp Franz von Siebold and Joseph Gerhard von Zuccarini in treatises of the Bavarian Academy of Sciences. Mathematical and natural science class, volume 4, number 3, page 230 published. In studies of germplasm, it was clearly distinguished from wax myrtle, and could be subdivided into two groups unrelated to the sex of the plant, but more so by the geographic region in China where the accession originated. Among regions in China, accessions varied within regions, indicating extensive gene mixing.

It is native to eastern Asia, mainly in south central China in province of Fujian, Guangdong, Guangxi, Guizhou, Hainan, Hunan, Jiangsu, Jiangxi, Sichuan, Yunnan, and Zhejiang; Japan, Korea, and the Philippines in forests on mountain slopes and valleys at elevations of and Yakushima macaques.

Chinese cultivation is concentrated south of the Yangtze River, where it has considerable economic importance and has been grown for at least 2000 years. It tolerates poor acidic soils. The root system is deep, with no obvious taproot. Myrica rubra was first introduced into the United States by Frank Nicholas Meyer from seed purchased from the Yokohama Nursery Co. in Japan and published in the Bulletin of Foreign Plant Introductions in 1918. Plants from the collection were grown and fruited in Chico, California and in Brooksville, Florida by David Fairchild. M. rubra is being commercialized in California by Calmei, a California corporation. Trees are prolific producers, with a single tree yielding some of fruit. As of 2007, 865,000 acres were devoted to yangmei production in Chinadouble the amount of acres utilized in apple production in the United States. The tree is used as ornaments for parks and streets. It is also a traditional tree used in composing classical East Asian gardens.

Archaeological and written evidence suggest that yangmei cultivation first took place in China over 2,000 years ago during the Han Dynasty. In Japan, it is the prefectural flower of Kōchi and the prefectural tree of Tokushima. The plant's name appears in many old Japanese poems.
