50. You will understand this better if I give you an exam- 
ple. You shall now analyze a flower in order to find its bota- 
nical arrangement and name. Here is a pink. We wish to 
know in what class it is—count the stamens—you sa ten, 
therefore this is in the tenth class; the name of the class is 
Decandria (from deka, ten, and andria, stamens.) 
51. We wish to know in what order this flower is—count 
the pistils—you say two, it then belongs to the second order of 
the tenth class; the name of this is Digynia (from dis, two, 
and gynia, pistil.) 
_ 52. Orders are composed of families of plants called genera, 
which is the plural of genus. 
_ 53. We must, as a third step in our analysis, learn to what 
genus this flower belongs; for this purpose it is necessary that 
you turn to that part of your book called “ Description of the 
Genera of Plants ;”* look for Class 10, Order 2.—Now instead 
of looking a whole book through, you have only to examine the 
genera which you find under this order, and to compare your 
flower with each description until you find one which answers 
to it. 
_ * To find this, see the “ Table of Contents,”
