Description. 
! HE Large-leaved Ma- 
ple is one of the most 
graceful of trees in the 
H^gH country it inhabits, va- 
rying from forty to ninety feet in height, and 
from two to five feet or more in diameter. The 
trunk is covered with a rough, brown bark, and 
the branches are wide and spreading. The 
leaves vary much in size, and also in the manner 
in which they are lobed. Som^ are cut nearly 
to the base, so as almost to merit the appellation 
of palmate, while others are not more deeply cut 
than those of the Acer platanoides. The largest- 
sized leaves are nearly a foot broad. The flow- 
ers are of a greenish-yellow, and very fragrant, 
appearing in April and May. The fruit is hispid, 
with elongated, slightly diverging, glabrous 
wings. 
Geography and History. The Acer macrophyllum is a native of the north- 
west coast of North America. It is found exclusively in woody, mountainous 
regions along the sea-coast, between forty and fifty degrees of latitude, and on 
the great rapids of the river Columbia. 
" This noble tree," observes Dr. Hooker, " was unquestionably discovered by 
Mr. Menzies, the first naturalist who visited the coast where it grows." Mr. 
David Douglass, who subsequently found it, prophetically adds, " It will, at 
some future time, constitute one of our most ornamental forest trees in England." 
It was introduced into Britain in 1812, where, however, it had not flowered in 
1835. The largest specimen of this tree is in the garden of the London Horti- 
cultural Society, where it attained a height of twenty-five feet in twenty-three 
years.
