from twenty-five to thirty feet high, with a wide vase-shaped crown 
made of numerous spreading and ascending branches and short branch- 
lets. The flowers are pale pink, more or less semidouble and very fra¬ 
grant: and the fruits are pale yellow, nearly globose, and about three- 
quarters of an inch in diameter. 
Males Scheideckeri is supposed to be a hybrid between M. spectab- 
ilis and some unknown species, possibly M. micromalus. It is a small 
pyramidal tree with small flowers produced in great abundance, and 
is well worth a place in every collection of these trees. 
Mains pnmifolia var. rinki, the Apple cultivated in Japan for its 
fruit before the advent of foreigners and of Chinese origin, has been 
mentioned in former Bulletins, notably that of May 15, 1916. The wild 
type of this apple was discovered by Wilson in central China in 1907. 
From seeds sent to the Arboretum plants were raised and one of them 
is now blooming for the first time; it is on Bussey Hill, in the collec¬ 
tion of Chinese Apples, Pears and Cherries. This is now a small tree 
about ten feet high, with flowers like those of the common Apple and 
fully an inch and a half across. The fruit of rinki is longer than broad, 
yellow with a reddish cheek or entirely red, and the persistent calyx 
is raised, and not depressed as in the common Apple. This is the wild 
parent of the race of Apples long cultivated in the Orient, and since 
it fruits freely in the hot moist valleys of central China equally as 
well as in the cold regions of northern Korea it may prove of value to 
pomologists in breeding new races of Apples. 
Space does not permit even a brief mention of all the species and 
hybrids of all the Asiatic Crabapples in the Arboretum collection. 
Among them, however, are trees suitable for the avenue, park or gar¬ 
den, shrubs for lawn borders and the slopes of banks, all absolutely 
hardy in the coldest parts of New England, and all to be depended upon 
to produce in spring blossoms in profusion. The plants grow quickly 
in good soil, love to have the breezes blow freely through their branches, 
and many of them begin to flower and produce fruit when only a few 
years old. In collections like that of the Arboretum they hybridize 
freely, and the species can only be propagated by grafting or budding. 
Asiatic Quinces. In the Shrub Collection many varieties of these 
plants are growing and are now in full bloom. The flowers vary from 
white, flesh, pink and salmon to scarlet and fiery crimson, and no 
group of plants has more vivid blossoms. The numerous forms are 
derived from the Chinese Chaenomeles lagenaria (better known per¬ 
haps as Pyrus japonica), and the true Japanese C. japonica (C. Maulei) 
and have been cultivated for many centuries in the gardens of China 
and Japan. 
The earliest of the Lilacs to bloom, the Chinese Syringa affinis and 
S. oblata, are in flower and the collection will probably be at its best 
about May 24th. The red-flowered Japanese Azalea ( Rhododendron 
Kaempferi) is just opening its flowers on Azalea Path, and Fothergillas, 
many Spiraeas, Pearl Bushes, many Honeysuckles, Barberries and 
other interesting plants will be in bloom when this Bulletin reaches its 
Boston readers.
