300 ARBORETUM ET FRUTICETUM BRITANNICUM. 
white ; June and July. Capsule inflated red ; ripe in September. Decaying 
leaves purplish red, mixed with yellow. Naked young wood light brown. 
Hardy, and very ornamental, from its abundance of white flowers, which are 
produced in corymbs, and resemble those of the Guelder rose; and from the 
numerous inflated reddish capsules which succeed the flowers. Propagated 
by division of the root; but sometimes by layers, or by cuttings of the 
young wood put, in autumn, in a shady border, in a sandy soil.
