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 +\g 
6 ft. high. It was introduced in 1736, and produces {x} 
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. 6d. each; at Bollwyller, 
80 cents; and in New York, 27 cents.

agree with Torrey, in thinking this merely a variety 
of H. arboréscens. 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 8ft. high. It was introduced in 1806, and = = 
flowers in July and August. H. gedrgica Lodd. Cat., ME ae 
ed. 1836, only differs from it in flowering a little (a 
later, and in being rather more robust. 749 %

and flowers in July and August. Its propagation and 
culture are the same as those of the preceding species.
