The Double-flowering Horse Chestnut grows to a large size, 

 and is much like the common Horse Chestnut ; but, when in bloom, 

 presents a far more beautiful appearance, the flowers being so 

 double as to resemble the Double Pink Hyacinth. The tree 

 flowers when quite young, and is readily propagated by grafting 

 on the common species. 



3L. flava is a native of our western and south-western states, 

 and is found growing to the height of eighty feet, and four feet 

 in diameter ; and has yellow flowers. 



M. glabra, or the Ohio Buckeye, is a tree with rough bark. 



The Cut leaf, Variegated leaf, and other species and varieties 

 of this tree, are suitable for streets, or the shrubbery. Some 

 of them are shrubs, or small trees, as M. parviflora, Califor- 

 nica, pavia, &c. M. rubicunda is a very handsome species, with 

 pink flowers. 



ACER. 



Acer, or the Maple Family. More than forty species of 

 Maple are known, of which ten belong to the United States, and 

 nearly all are desirable ornamental shade trees. The common 

 species of New England are the Red Maple, Rock Maple, and 

 White Maple, all first-rate shade trees. We have, also, the 

 Striped and Mountain Maple, smaller trees, not so well known as 

 the others, and interesting in large plantations. 



" The Red Maple, called also the White, Swamp, Scarlet, and 

 the Soft Maple, is a tree of middling size, growing abundantly in 

 the swamps and low grounds in most parts of the state. Its 

 flowers, which appear in April or May, before the leaves, are of 

 a bright crimson or scarlet, and make a striking appearance in 

 whorls, or pairs, of sessile-crowned bunches, on the scarlet or pur- 

 ple branches. The Red Maple is usually a low, round-headed 

 tree, of less beauty of shape than either of the other species. But 

 the great variety of rich hues, which it assumes earlier in the fall 

 than any other tree, gives it a conspicuous place in our many- 

 colored landscape." It is a tree of very rapid growth, and, al-
