.ffiSCULUS (ancient name of some oak, or mast-bear- 

 ing tree). Sapinddcece. Horse-chestnut. Buckeye. 

 Deciduous trees and shrubs : lvs. opposite, long-petioled, 

 digitate ; leaflets 5-7, large, serrate : fls. symmetrical in 

 terminal, showy panicles; petals 4—5, stamens 5-9: fr. 

 a large trilocular capsule with 1-6 seeds. N, Amer., E. 

 Asia, Himal., N. Greece. Ornamental trees and shrubs 

 with handsome fls.; hardy except the Californian and 

 Himalayan species, growing best in moist and loamy 

 soil. The larger- growing species are excellent shade 

 trees, and the fls. are showy and interesting. The fr. is 

 not edible. Prop, by seeds, to be sown in the fall or 

 stratified, or by grafting and budding on common species, 

 and the shrubby forms also by layers. ^. parvifXora 

 prop, also by root-cuttings. 



A. Winter-huds resinous: claws of the petals not longer 



than the calyx; stamens exserted.

 ate-obovate, acuminate, obtusely serrate, nearly gla- 

 brous : panicles 8-12 in. long, very showy ; fls. white, 

 tinged with red : fr. echinate. May, From HiniahivM.s to

 var. heterophylla , Hort.), leaflets laciniate. Var. M6m> 



mingeri, Hort., leaflets dotted with white. Some other 

 variegated forms. The horse-chestnut is one of the most 

 pHpular of shade trees on the continent of Europe, and 

 is also much planted along roads and in parks and private 

 grounds in this country. It is particularly adaptable for 

 bowers and places where seats are desired, as the top 

 stands heading-in and makes a very dense shade. Hardy 

 in the N. states.
