A genus, Aesculus, of deciduous trees or shrubs belonging to the plant order Sapindales. Buckeyes grow in North America, southeast Europe and eastern Asia (including India). The distinctive features of buckeyes are opposite, palmately compound leaves and a large fruit having a firm outer coat and containing usually one large seed with a conspicuous hilum [the scar on a seed marking the point of detachment from the funiculus (stalk of an ovule)]. The Ohio buckeye (A. glabra) [see illustration], a small tree that may grow to a height of 9 m (30 ft), is found mainly in the Ohio valley and in the southern Appalachians. It can be recognized by glabrous (smooth) winter buds, prickly fruits that are 2.5–5 cm (1–2 in.) in length and compound leaves that have five leaflets.
