nearly all fertile. Flower buds obtuse. Flowers white, 

 small, having an agreeable odour. (Don's Mill., iii. 

 p. 232.) This species is found wild from Pennsylvania 

 to Virginia, where it forms a shrub, growing from 4 ft. to 

 6ft. high. It was introduced in 1736, and produces 

 its flowers in July and August. It prefers a moist soil, t 

 and is readily propagated by division of the root. Plants, 

 in the London nurseries, are \s. (/. each; at Bollvvyller,

Spec. Char., Sfc. Leaves broadty ovate, acuminated, 

 rather cordate at the base, coarsely toothed, gla- 

 brous beneath. Flowers all fertile. Flowers small, 

 white, sweet-scented. (Don's Mill., iii. p. 232.) We 

 agree with Torrey, in thinking this merely a variety 

 of H. arborescens. It is a native of Carolina, on the 

 mountains, and on the banks of the Missouri, above 

 St. Louis ; where it forms a shrub, growing from 

 lift, to 8ft. high. It was introduced in 1806, and 

 flowers in July and August. H. gcorgica Lodd. Cat., 

 ed. 1836, only differs from it in flowering a little 

 later, and in being rather more robust.

Spec. Char., <$c. Leaves cordate, oval, acuminated, sharply 

 toothed, clothed with white tomentum, or pubescence, 

 beneath. Corymbs flattish. Sepals of sterile flowers 

 entire. Flower buds depressed. Flowers white, rather 

 large. (Don's Mill., iii. p. 232.) It is found wild near 

 the Savannah river, where it forms a shrub, growing 

 from 4ft. to 6ft. high. It was introduced in 1786, 

 and flowers in July and August. Its propagation and 

 culture are the same as those of the preceding species.
