not perhaps a more beautiful Crabapple in cultivation. Like other hy- 
brids, it can only be increased by grafts or cuttings, and is still rare in 
gardens. A better known hybrid of M. jioribunda, M. Scheideckeri 
appeared in Germany several years ago. The broad pyramidal habit 
of this tree suggest M. spectabilis which is probably the other parent. 
This hybrid flowers here earlier than M. fioribiinda. The bright rose 
pink flowers which are often semidouble are produced in great profu- 
sion and are followed by bright yellow fruit sometimes three-quarters 
of an inch in diameter. The excellent habit and early flowers of this 
hybrid make it a valuable addition to the group. 
Malus Sieboldii was introduced from the gardens of Japan into Eu- 
rope by Von Siebold in 1853. It is a low, dense shrub of spreading 
habit with the leaves on vigorous branchlets three-lobed, small flowers 
tinged with rose in color, and small yellow fruits. Von Siebold 's Crab 
is really a -dwarf form of a tree common on the Korean Island of 
Quelpaert, and on the mountains of central Japan and Hokkaido, to 
which the name var. arborescens has been given. This is a tree often 
thirty feet or more tall, with ascending wide-spreading branches, twiggy 
branchlets and minute fruit yellow on some and red on other individuals. 
Although the flowers are small, they are produced in immense quanti- 
ties, and this species has the advantage of flowering later than the 
other Asiatic Crabapples. Malus atrosanguinea is believed to be a 
hybrid of M. Sieboldii and the Parkman Crab. It is a broad-branched 
low tree with rather dull red showy flowers and is now often seen in 
American gardens. 
Malus Sargentii from salt marshes in the neighborhood of Muroran 
in northern Japan, where it was discovered by Professor Sargent in 
1892, has qualities which give it a field of usefulness peculiarly its own. 
This species is a dwarf with rigid and spreading branches, the lower 
branches flat on the ground. The flowers are in umbel-like clusters, 
saucer-shaped, round and of the purest white, and are followed by 
masses of wine-colored fruit which is covered by a slight bloom and 
unless eaten by birds remains on the plants well into the spring. The 
plant usually sold by American nurserymen as M. Sargentii is probably 
a hybrid of this species. It is dwarf although treelike in habit with a 
well formed stem, short spreading branches and small flowers tinged 
with pink. 
Malus prunifolia rinki is an interesting tree, for this is the Apple 
cultivated by the Chinese and from China taken to J apan where it was 
the only Apple cultivated as a fruit tree before the advent of foreigners. 
The wild type of this tree discovered by Wilson in western China is 
also growing in the Arboretum. Malus sublobata is the name which 
has recently been given to a Crabapple of unknown origin believed to 
be a hybrid of Malus prunifolia rinki and M. Sieboldii. The plants 
of this hybrid are, with a single exception, narrow, pyramidal, fast- 
growing trees taller than any other Crabapple in the collection, and 
looking now as if they might grow into big trees. This hybrid does 
not flower in the Arboretum very freely every year and the flowers are 
mostly confined to the upper branches.
