Bud and flower of jewel-weed, or "touch-me-not." A. 

 Interior of bud. Stamens are seen, but there appears to be 

 no pistil. B. Section of bud showing the pistil concealed 

 behind the stamens. C. Bee entering flower comes in con- 

 tact with stamens and is loaded with pollen. D. Same bee 

 entering older flower. The stamens have ripened and been 

 pushed off by the lengthened pistil, which is brushed by the 

 back of the bee, and thus is pollinated. This is a con- 

 trivance to insure cross-pollination.
