This shrub-like cherry is very generally cultivated in central, eastern and northern China and in Japan for its fruit and as an ornamental. It has been introduced into cultivation in many widely separated places in North America and appears to be promising for cold regions, both bud and wood withstanding perfectly the most rigorous climates of the United States. As it grows in America it is a bush and never a true tree. It is a twiggy, close-jointed plant, usually with many stems springing from the ground and these bearing branches quite to the base. Frequently these low-growing branches bend to the ground and take root forming new plants. The bushes are thickly clothed with leaves densely tomentose on the underside, in this respect and in shape, as well, very unlike the foliage of common cultivated cherries. The flowers appear in great abundance with the leaves, making a handsome ornamental; they are white, becoming rose-colored as they fall away. The fruit ripens in mid-season for cherries, setting profusely from the many blossoms. The cherries are a half-inch in diameter, bright currant-red, covered with inconspicuous hairs and contain a stone of medium size. They are pleasantly acid, very juicy and withal a decided addition to cultivated cherries. _Prunus tomentosa_ seems a most promising plant for domestication and of particular merit for small gardens and cold regions. Koehne, in his list of cherries, names ten botanical varieties of _Prunus tomentosa_. From this the species seems to be most variable and under cultivation would probably break up into many forms some of which might prove superior to the type species. Koehne's botanical varieties are given under the species on page 22. PRUNUS PUMILA Linnaeus. 1. Linnaeus _Mant. Pl._ 75. 1768. 2. Bailey _Cor. Bul. Ex. Sta_. =38=:96. 1892.
