gentian family may be found a little beyond the plumbago 

 family; various gentians are represented, among them the 

 blind gentian, a native of the United States. In the brook, 

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

 bean family; here are shown the water-snowflake, common 

 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- 

 tives are the common milkweed of our roadsides, the hairy 

 milkweed and the swamp milkweed; the swallowworts also 

 belong here and are illustrated by several species. In 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 

 bush morning-glory from the western United States. 

 Following the milkweeds is the phlox family; interesting 

 plants here are the Jacob's-ladder {Polemonium), of 

 Europe, with its masses of blue flowers; the hairy phlox, 

 of North America; Brittons' phlox, a relative of the common 

 ground phlox, from the southeastern United States; the 

 ground phlox and its white-flowered form, both natives of 

 the eastern United States; and forms of the garden phlox, 

 also from the southeastern United States. In the shade, 

 the natural habitat of many of these plants, is the water- 

 leaf family, at the base of a large rock on the ridge; there 

 are the purple, the broad-leaved and the Virginia water-leaf 

 (Hydrophyllum) . 



Further along and at the base of the ridge is the borage 

 family; the tuberous comfrey, the rough comfrey and the 

 common comfrey, all natives of Europe, are represented. 

 In the vervain family, in a small bed to the left, may be 

 found: the wedge-leaved fog-fruit (Lippia), from the wes-
