Calycifloral when they are upon the calyx (stamens 

 perigynous or epigynous-). 



Corollifloral or Epipetalous when they are upon the 

 corolla. 



Gynandrous when they are upon the pistil.* 



But sometimes these differences are difficult to 

 distinguish, and it may sometimes help you to trace 

 a plant from its class to its natural' order if you use 

 the artificial system of classification. 



And now you want to know what this artificial 

 system is ? Well, the system of classification which 

 I have been hitherto telling you about is called the 

 " natural system." It is so called because plants are 

 arranged in it according to their natural similarities. 

 Other systems have been' made which are called 

 artificial. They are so called because plants are 

 grouped together in -them which are alike in some 

 special features, but which are often very unlike each 

 other in their general natural characteristics. The 

 artificial system I shall tell you of is the one which' 

 was made by the great Swedish botanist Linnaeus, 

 and so it is generally called the Linnaean system. 



In this plants are grouped in twenty-four classes, the 

 spermaphytes into twenty-three of them, the twenty- 

 fourth including all the other plants. These 

 twenty-three classes are arranged according to the 

 numbers and position of the stamens. If you
