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 

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

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

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

 in the London nurseries, are Is. 6rf. each; at Bollwyller, 

 80 cents ; and in New York, 27 cents.

Spec. Char., efc. Leaves broadly 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 

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

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

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

 later, and in being rather more robust.

 toothed, clothed with white tomentum, or pubescence, 

 beneath. Corymbs flattish. Sepals of sterile flowers 

 entire. Flower buds depressed. Flowers white, rather sj 

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

 the Savannah river, where it forms a shrub, growing 

 from 4 ft. to 6 ft. 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.
