 agree with Torre}', 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 slu-ub, growing from 

 6 ft, to 8 ft. 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,
