126 ARBORETUM ET FRUTICETUM BRITANNICUM. 
According to Michaux, the American horsechestnut is commonly a bush or 
low tree, from 10 ft. to 12 ft. in height ; but it is sometimes 30 or 35 feet high, 
trunk 12 or 15 inches in diameter. He found it only on the banks of the Ohio : 
but Torrey and Gray give as its habitats the western parts of Pennsylvania, 
Virginia, Ohio, Kentucky. The tree in the Hort. Soc. Garden is of equally 
Hagen growth with the common horsechestnut ; the leaves are larger, and 
of a bright green: on the supposition that this is the Z. ohioénsis of Miche. and 
Tor. Gray, we have no doubt in our own mind that it is only a variety of the 
common horsechestnut, Dr. Lindley, however, is of a different opinion, con- 
sidering it as a distinct species. (See Bot. Reg., 1838, t. 51.)

Spec. Char., §c. Petals 4, with the claws shorter than the calyx. The 
flowers are scarlet, and very ornamental ; the leaves of a deeper green than 
those of any other sort, and they have a red spot at the base of the petioles 
of the leaflets on the under side. The flowers come out of a dark red, and 
die off still darker. Fruit prickly. A deciduous tree, below the middle 
size. ? Hybrid from North America, Height 20 ft. to 30ft. Cultivated 
in 1820. Flowers red; May and June. Fruit brown; ripe in October. 
Tt is doubtful whether this tree is a native of North America, or originated 
in British gardens. It passes under different names in different nurseries,

as will be seen by our list of synonymes, and may be considered as differing 
little, if at all, from 4. carnea Lindl, It is distinguished from Pavia ribra 
by its larger and rougher leaves ; and from 4. Hippocdstanum by the leaves
