Description. 



^HE Large-leaved Ma- 

 ple is one of the most 

 graceful of trees in the 

 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. Some 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.
