just beyond the little stone bridge, may be found the buck-

in tropical regions, and the water-lily floating heart, native 
in Europe and northern Asia. 
Just beyond the left-hand bed devoted to the carrot 
family is the dogbane family; the willow-leaved amsonia, 
from the central and southeastern United States,.and the 
broad-leaved amsonia, from the central and eastern United 
States, are conspicuous objects here. Beyond this are 
two beds of the milkweed family and among its representa-

milkweed and the swamp milkweed; the swallowworts also 
belong here and are illustrated by several species. 'n the 
morning-glory family, located to the right of the above, 
are the small bind-weed, of northern Europe and Asia, 
sometimes a troublesome weed in this country, and the
