worth a place in collections for its beautiful fruit valuable for cooking 
and jellies. The so-called Mammoth Crab is probably only a selected 
form of this species. 
Malus fusca, the only native Apple-tree of the Pacific States, where 
it ranges from Alaska to central California, is in flower. This differs 
from the other American Crabapples in its short-oblong, yellow-green 
flushed with red or nearly entirely red fruit from half an inch to three- 
quarters of an inch long, without the waxy exudation which is peculiar 
to the eastern American species, and with thin dry flesh. The calyx of 
the flower, unlike that of the eastern species but like that of many 
Asiatic species, falls from the partly grown fruit. 
Malus angustifolia is the last Crabapple in the Arboretum to flower. 
This is a tree sometimes thirty feet tall with a trunk eight or ten 
inches in diameter, and wide-spreading branches, bright pink exceed- 
ingly fragrant flowers an inch in diameter, and depressed globose fruit. 
From the other species it differs in the only slightly lobed or serrate 
leaves on the ends of vigorous shoots and in the rounded apex of the 
leaves on flower-bearing branchlets. Malus angustifolia is a southern 
species which naturally does not grow north of southeastern Virginia 
and southern Illinois, ranging to northern Florida and western Louisi- 
ana. Plants raised here many years ago from seed gathered in north- 
ern Florida are perfectly hardy in the Arboretum where they bloom 
every year late in May and have proved to be handsome and valuable 
plants here. The other American species, M. glabrata of the high val- 
leys of the mountains of North Carolina, M. lancifolia, widely distrib- 
uted from Pennsylvania to Missouri and western North Carolina, and 
Malus bracteata, a common species from Missouri to Florida, with 
many of the varieties of Malus ioensis, are now established in the 
Arboretum but the plants are still too young to flower. 
Malus Soulardii, which is believed to be a natural hybrid between 
M. ioensis and some form of the orchard Apple (M. pumila), not rare 
and widely distributed in the middle west, is a tree as it grows in the 
Arboretum, nearly as broad as it is high with spreading slightly droop- 
ing branches. It has not before this year been as thickly covered with 
its pale pink fragrant flowers which for ten days at least made it one 
of the most attractive objects in the Crabapple collection at the east- 
ern base of Peter’s Hill. It is a curious fact that M. Soulardii flow- 
ers in the Arboretum fully two weeks earlier than either of its sup- 
posed parents. Several varieties of Soulard’s Crab are distinguished 
by western pomologists. Some of them are in the Arboretum collec- 
tion, but the “Fluke Apple” is the only one which has flowered here 
yet. This resembles Soulard’s Crab in size and shape, and in the color 
of its equally abundant flowers, and as an ornamental plant is of equal 
value. 
Malus Dawsonii is a hybrid of the western M. fusca and the com- 
mon Apple which appeared in the Arboretum many years ago from 
seed collected in Oregon. It has grown here to more than double the 
size of M. fusca, to which it shows its relationship in the oblong fruit
