 Deciduous trees and shrubs : lvs. opposite, long petioled 

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

 terminal, showy panicles; petal.s 4-5, stamens 5-9 fi 

 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 Califomian 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 

 stratifled, or by grafting and budding on common species, 

 and the shrubby forms also by layers. ^. parviflora 

 prop, also by root-cuttings. 



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



than the calyx; stamens exserted. 



B. Petals 4-5; calyx campanulate, 5-lobed; stamens 



5-8: fr. globular. (Bippoeastanum.) 

 Hippoo48tanum, Linn. Common Horse-chestnut. 

 Fig. 43. Large tree, 60-80 ft. ; leaflets 5-7, sessile, cune- 

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

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

 tinged with red : fr. echinate. May. Prom Himalayas to 

 N. Greece.— Many garden forms, as var. fldre plSno, with 

 double fls.; bears no fr. I.H. 2: 50. Var. pilmila, Dipp. 

 Dwarf form. Var. umbraculifera, Hort., with compact, 

 roundish top. Var. lacini&ta, Dipp. (var dissecta, Hort., 

 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 

 piipular 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.
