hybridization among the Apples, while it makes endless trouble for 
the systematic botanist, has advantages for the gardener, as has 
already been seen in the Arboretum where one of the most beautiful of 
all flowering Apples, now called Malus Arnoldiana, appeared a few years 
ago among seedlings of M. floribunda. This plant is also shrubby in 
habit, with flowers more than one-half larger than those of M. flori- 
bunda and much larger fruits. It is probably a hybrid with some of 
the large-flowered hybrids of the Siberian Malus baccata. Near the 
Administration Building are large seedling plants raised from M. flori- 
bunda which are peculiar in their persistent fruit which remains in 
good condition on the branches until spring and supplies the birds with 
an abundant supply of winter food. Another supposed hybrid between 
two species of eastern Siberia, sometimes called Malus cerasifera , is 
common in the Arboretum in various forms. With plenty of space this 
grows into a large, wide-spreading tree. The pure white flowers 
are perhaps larger than those of any of the other Crabapples. The 
fruit on different plants varies in color and greatly in size and shape, 
on some trees retaining and on others losing the calyx. Selected 
forms of this tree can only be obtained by grafts. Malus Halliana, 
usually known as the Parkman Crab, was found in Japanese gardens 
by Dr. Hall and sent to the United States in 1861 in the first consign- 
ment of plants to reach the United States direct from Japan, and was 
first cultivated by Francis Parkman, the historian, in his garden on 
the shores of Jamaica Pond, now in the Boston Park System. This is 
a treelike shrub with erect and spreading stems and is smaller than 
Malus floribunda, differing from it in its darker bark, thicker leaves 
deeply tinged with bronze color when they unfold, and semidouble, bright 
rose-colored flowers drooping on long slender stems, and in its smaller 
fruit which is not larger than a small pea. Some persons consider 
this the most beautiful of the Crabapples, and certainly the color of 
the flowers is unlike that of any of the others. The origin of this 
plant was unknown till Wilson found it growing in western China near 
the borders of Tibet. Another Chinese Crab, Malus spectabilis, is 
usually found in gardens only in the form with double or semidouble 
flowers. It is a tree with erect, slightly spreading stems which form 
a vase-like head, and in some of its forms is an attractive and useful 
plant. Malus Scheideckeri, which is no doubt a hybrid although of 
uncertain origin, is a small tree of pyramidal habit which usually pro- 
duces its comparatively small pink flowers in such profusion that it 
should find a place in every collection of these plants. Malus (. Pyrus ) 
toringo was first used as a name for a Japanese Crabapple, and there 
are two or three Japanese forms in the collection here under that 
name. In 1882 the Arboretum received from Dr. Bretschneider, then 
at Pekin, seeds of a Crabapple which has been growing here ever since 
and has been considered a form of the Japanese M. toringo from which, 
however, it differs in its much smaller and later flowers and smaller 
fruits which on some individuals are red and on others yellow. Al- 
though one of the least showy of the Crabapples, this Chinese tree is 
valuable as it flowers after the others have passed. Two other Japan- 
ese species are well represented in the collection from seeds collected
