and obscure. It is light orang-e-colored with a thin, rather Hghter colored sapwood composed of twel 

 or fifteen layers of annual growth. The specific gravity of the absolutely dry wood is 1.0459 a cub* 

 foot weighing 65.18 pounds. It furnishes excellent fuel, and is used for this purpose by the inhabit- 

 ants of the Florida keys. The hardnesSj strength^ and durabihty of this wood would make it valn^W 

 in the arts if it could be obtained in large quantities. 



The earliest account of Amyris maritima appears to be that of Catesby, who published in hi^ 

 Natural History of Carolina a very good figure of the small-leaved littoral variety,^ It was first 

 noticed in Florida on the east coast in 1821 by Mr. N. A. Ware,^ and was collected later on Key West 

 by Dr. J. L. Blodgett.
