_ Miil., i. p.648.) Flowers polygamous. A deciduous tree, a native of the 
mountains of Canada, and of the Alleghany Mountains ; producing its very 
_small greenish flowers in April and May, and attaining in its native 
country, according to Michaux, the height of 6 ft. or 8 ft. Introduced in 
1750, by Archibald Duke of Argyle, and about as common in ornamental 
plantations in England as A‘cer tatéricum., In British gardens, it forms a 
low tree, 8 ft. or 10 ft. high, very ornamental in autumn, from its small keys, 
which are fixed upon slender pendulous spikes, and have their mem- 
branous wings, beautilully tinged with red when ripe. Michaux states that 
this species, grafted uponthe sycamore, is, like the A‘cer striatum, augmented 
_ to twice its natural dimensions ; a fact which we have never had an oppor- 
tunity of seeing verified. 
Statistics. At Syon, 25 ft. high. In Worcestershire, at Croome, 30 years

Society’s Garden, 9 years planted and 30 ft. high. Price, in London, 1s. 6d.

Spec. Char. Leaves cordate, 3-lobed, acuminated, finely and acutely, 
serrated. Racemes pendulous, simple. Petals oval. Fruit smooth, with 
the wings rather diverging. (Don’s Mill.,i. p.643.) A tree readily distin- 
guished by the striped bark of the young shoots, growing in its native coun- 
try to the height of 10 ft. or 12 ft., but to that of 20 ft. or upwards in a 
state of cultivation. It produces its flowers in May and June, and some- 
times ripens seeds. 
Description, §c. The trunk and branches are covered with a smooth green 
bark, longitudinally marked with black and white stripes, by which the tree is 
readily distinguished at all seasons of the year. In America, it is one of the 
first trees that announces the approach of spring. Its buds and leaves, when 
beginning to unfold, are rose-coloured. The leaves are of a thick texture, and 
finely serrated. The flowers are greenish, and are grouped on long peduncles. 
The fruit is remarkable for a cavity on one side of the capsules. It is a native 
of Norta America, in Nova Scotia, and from Canada to Carolina. It makes 
its first appearance in about latitude 47°, and is particularly abundant in Nova 
Scotia, the State of Maine, and New Hampshire. In approaching the 
Hudson, it becomes more rare ; and, beyond this boundary, it is confined to the 
mountainous tracts of the Alleghanies, in which it is found in cold shaded 
exposures, along the whole range to its termination in Georgia. In many of 
the forests of Maine and New Hampshire, A. striatum constitutes a great part 
of the undergrowth, seldom exceeding 10 ft. in height; but, where it is not 
shaded by other trees, it attains the height of 20 {t. or upwards, The wood 
is white and fine-grained, and used by cabinet-makers as a substitute for holly. 
Cattle, in Nova Scotia, are fed with the leaves, both in a green and dried 
state; and in spring, when the buds begin to swell, both horses and cattle are 
turned into the woods to browse on the young shoots, which they consume 
with avidity. (ichauw.) From the great beauty of its bark, this. tree de 
serves a place in every collection. It is propagated by seeds, which are re« 
ceived from America, or by grafting on A. Psetdo-Piétanus. 
Slaiistics. The largest specimen which we know of within a short distance 
of London,is at Mr. Needham’s villa,near Maidenhead, where it has attained the 
height of 16 ft. 6in. in 20 years. Near Reading, at White Knights, a tree 25 years 
planted is 21 ft. high; in Surrey, at Farnham Castle, 35 years planted, it
