sometimes a troublesome weed in this country, and the 
morning-glory. 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; Britton’s 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, 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). 
Farther 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 vervains. We now come in the sequence to 
the mint family, to which are devoted six beds; among 
the true mints may be found here the creeping whorled 
mint, the curled mint and the spearmint, all from the 
Old World. Many familiar plants may be seen in these 
beds, and among them are: the false dragon-head, of the 
United States; motherwort, common in Europe and widely 
distributed as a weed in this country along roadsides and 
in waste places; the horse-balm, of North America, common 
in the east in woods; Oswego tea, and other bergamots, 
natives of North America; the betony and hyssop, of 
Europe; the hedge-nettles, from both the Old World and 
the New; the common sage of the Mediterranean region, 
highly ee by the housewife, and other sages; catnip, 
a native of Europe, but widely distributed as a weed in 
this country; Gill-over-the-ground, or ground ivy, also 
a European plant, but extensively spread as a weed in 
this country; and the dittany, of North America. 
The potato family may be found a little to the left and 
just beyond the phlox family. Here may be seen the
