These beautiful plants are found along shaded streams and 

 marshes, and are profusely hung with brilliant jewel-like flowers 

 during the summer months. In the later year they bear those 

 closed inconspicuous blossoms which fertilize in the bud and are 

 called cleistogamous flowers. The jewel- weed has begun to ap- 

 pear along the English rivers, and it is said that the ordinary 

 showy blossoms are comparatively rare, while the cleistogamous 

 ones abound. Does not this look almost like a determination on 

 the part of the plant to secure a firm foothold in its new envi- 

 ronment before expending its energy on flowers which, though 

 radiant and attractive, are quite dependent on insect visitors for 

 fertilization and perpetuation? 



The name touch-me-not refers to the seed-pods, which burst 

 open with such violence when touched, as to project their seeds 

 to a comparatively great distance. This ingenious mechanism 

 secures the dispersion of the seeds without the aid of the wind or 

 animals. In parts of New York the plant is called ''silver-leaf," 

 from its silvery appearance when touched with rain or dew, or 

 when held beneath the water.
