Besides these well-recognized species of cultivated cherries there are several others that play a much less conspicuous part in horticulture. Prunus fruticosa Pallas, the Dwarf Cherry of Europe, is much cultivated, more especially its botanical variety pendula, as an ornamental and somewhat for its fruit. According to Wilson,1Prunus involucrata Koehne is grown for its fruit in the gardens of China; the fruits, he says, are "small and lacking in flavour."The fruits of Prunus emarginata Walpers are eaten by the Indians on the Pacific Coast and the early settlers used the species as a stock for orchard cherries. Prunus jacquemoniii Hooker, the Dwarf Cherry of Afghanistan and Tibet, is occasionally in culture for its fruit and as a park plant; so also is another dwarf cherry from southwestem Asia, Prunus incana Steven. Prunus pseudocerasus Lindley, the Flowering Cherry of Japan, is a well-known ornamental the world over and in Japan is used as a stock for orchard cherries for which purpose, as we have suggested in the discussion of stocks, it ought to be tried in America.
