_j*j tree or shrub, 
fifteen or twenty feet in height, found 
in greater or less abundance in rocky 
places, and on the banks of streams 
which issue from the Alleghanies, from 
Canada to Georgia. Its head is close 
and compact, with branches armed with 
very long, slender, sharp spines. Its 
leaves are of a deep, shining green, and 
vary, exceedingly, in size, according to 
the age and vigour of the tree. They 
are usually from one to two inches in 
length, and are often deeply, and near- 
ly equally three-lobed, like those of the 
red-flowered maple, being sometimes 
of a slightly rhombic form, and a little tapering at the base. The flowers, which 
appear by the end of June or the beginning of July, are produced in numerous 
terminal corymbs, and are succeeded by very small, depressed-globose, bright-pur- 
ple fruit. This species has been cultivated in Britain since the year 1738, where 
several fine specimens are growing, of a height of fifteen to thirty feet. It was 
first cultivated in the nursery of Mr. Main, of Georgetown, in the District of 
Columbia, towards the close of the last century, and has since been much 
employed in other parts of the United States for hedges, under the name of 
"Washington Thorn."
