There are several species of Horse-chestnut, but the common one (�sculus Hippocastanum) is incomparably the finest. The American sorts are the following: (�sculus Ohioensis,) or Ohio Buckeye, as it is called in the western states; a small sized tree, with palmated leaves consisting of five leaflets, and pretty, bright yellow flowers, with red stamens. The fruit is about half the size of the exotic species. The Red-flowered Horse-chestnut (�sculus rubicunda) is a small tree with scarlet flowers; and the Smooth-leaved (�. glabra) has pale yellow flowers. All the foregoing have prickly fruit. Besides these are two small Horse-chestnuts with smooth fruit, which thence properly belong to the genus Pavia, viz. the Yellow-flowered Pavia (P. lutea) of Virginia and the southern states; and the Red-flowered (P. rubra), with pretty clusters of reddish flowers; both these have leaves resembling those of the Horse-chestnut, except in being divided into five leaflets, instead of seven. There are some other species, which are, however, rather shrubs than trees.
