country, must be matter of gratulation to every lover 
of the science of botany. T o the exertions of one

ticultural Society, Great Britain is indebted for two 
hundred living species of American plants, nearly 
all them quite hardy, and now forming the princi- 
pal ornaments of our gardens. Douglas, to whom
