is the loosestrife family, represented by the purple loosestrife, 
a native of Europe, but introduced in many places in this 
country ; among others belonging to this family is the swamp 
loosestrife or willow-herb (Decodon), a plant of which will 
be found along the brook opposite to the loosestrife bed. 
Near this, on the edge of the brook, is located the meadow 
beauty, one of the prettiest little flowers of our meadows. It 
belongs to the meadow-beauty family, few species of which 
occur in cool regions; it is largely represented in warm tem- 
perate and tropical regions, and many other species will be 
found in the conservatories. Buta short distance from the 
violet family is the evening-primrose family; here will be 
found a number of the evening primroses (Oenothera), with 
their showy yellow flowers, noteworthy as the plants mainly 
experimented with by Professors DeVries and MacDougal in 
their studies on the origin of species. Along the brook, not 
far from the loosestrife family, is the water-milfoil family, 
represented by the Chilean water-milfoil or parrot’s-feather, 
forming a beautiful mass of feathery green on the surface of 
the water. Returning now to the ridge, a little beyond the 
violet family, we find the bed allotted to the ginseng family ; 
here are the Indian-root, from eastern North America, and 
the heart-leaved aralia from Japan. To this family also 
belongs the ginseng plant, the root of which is so much 
prized by the Chinese as a medicine. Down the slope from 
this group will be found two beds given over to the carrot 
family, which includes many economic plants, such as the 
carrot, parsnip, celery, and spinel ; OUaBe: a common 
European plant, is shown, and the r master, from 
the eastern United States; the at carrot and the golden 
meadow parsnip also belong here. 
To the primrose family, located at the base of the ridge a 
little beyond the carrot family, belong the primroses (Premuda), 
many of which are natives of Europe; here we find the com- 
mon European primrose, the cowslip, and others; the money- 
wort, a native of Europe, but introduced into many places in 
this country, sends its long creeping stems all over the bed—
