PINK FAMILY. CARYOPHYLLACEAE. 



This rather large family of herbaceous plants includes such a variety that it is 

 difficult to define to any except botanists. It contains many sorts of pinks and 

 carnations, and is one of the families abounding in weeds. 



There are about 1,500 species, most abundant in the northern hemisphere, especially 

 in Europe.
