leaves begin to appear the following spring. The unusual habit of this 
plant makes it useful for covering slopes and banks, or to form an 
edging to beds of taller shrubs. With abundant space it may be ex- 
pected to form a bush eighteen or twenty feet in diameter. 
Malus Sieboldii is a Japanese species with the leaves at the end of 
vigorous branches deeply three-lobed. It grows in two forms; as a 
shrub only three or four feet high with wide-spreading and arching 
stems, and as a small tree (var. arborescens) with a well-formed trunk 
and horizontal branches which form a rather flat-topped head. This is 
the last of the Asiatic Crabapples in the collection to flower and only 
a few of the bright red flower-buds are open. The flowers are small, 
white, and produced in profusion every year. The fruit is not larger 
than a small pea, and is bright red on some plants and yellow on oth- 
ers. What has been considered a variety of Malus Sieboldii (var. cal- 
ocarpa) is a larger growing plant with larger flowers which open ten 
or twelve days earlier and are rose pink, finally becoming white; the 
fruit is much larger, bright red, lustrous and persistent. This plant 
produces large crops of flowers and fruits every year and in both spring 
and autumn it is one of the handsomest of the Asiatic Crabapples. It 
is not known as a wild plant in Japan and is probably exceedingly rare 
in cultivation in western countries. For this beautiful plant the Arbor- 
etum is indebted to Dr. William Sturgis Bigelow of Boston who brought 
the seeds from Japan in 1889. 
Malus sublobata. This is believed to be a hybrid and it has been 
suggested that it is the result of a cross between Malus pruni folia 
rinki and M. Sieboldii. The plants in the Arboretum are of very un- 
certain origin but it is probable that they were raised from seeds sent 
from Japan, although for several years and until the plant flowered 
they were supposed to be Malus sikkimensis. The Arboretum trees 
are already thirty feet high and, unlike other Crabapples, form a tall 
trunk covered with pale bark and a narrow head, and in shape are not 
unlike a young Ash or Tulip-tree. The large white flowers are chiefly 
produced on upper branches and are followed by bright clear yellow 
fruits about three-quarters of an inch in diameter. No other Crab- 
apple in the collection produces such beautiful yellow fruit. For the 
beauty of its fruit, its unusual habit, vigor and rapid growth, Malus 
sublobata is well worth the attention of planters. 
Malus Soulardii is believed to be a hybrid of the Apple-tree of east- 
ern Europe {M. pumila) and of the wild Crab of the Mississippi valley, 
Malus ioensis, and trees of this hybrid are not rare in the woods in 
the region from Indiana to Iowa. In the Arboretum Malus Soulardii 
is a round-headed tree in shape like its eastern parent; the flowers are 
pink, and smaller than those of either parent; the fruit is green, de- 
pressed-globose, from an inch to two and a half inches in diameter, 
and without the waxy exudation which is found on the fruit of the 
Crabapples of eastern North America. The trees are covered with 
flowers this year. As a natural hybrid of much interest and as a 
flowering plant Malus Soulardii is well worth a place in collections of 
these trees. As fruit trees this hybrid and its American parent are 
worth growing, for jelly made from the fruit of the Iowa Crabapple
