Aesculus hippocastanum (Horse chestnut) Hippocastanaceae (Buckeye family)
The tree with a gnarled trunk growing across the road from Morrill Hall.

  Native to south-west Asia and the Balkan Peninsula, the horse chestnut was introduced to the US in colonial times and now grows throughout the country. The horse chestnut is not a "chestnut" at all, but a relative of the native Ohio buckeye. The horse chestnut is our largest non-native, spring-flowering tree, reaching a height and spread of 50 to 75 feet. The leaves are palmately-compound, consisting of 5 to 7 leaflets. The showy flowers are produced in May and June in large, upright panicles.
