4 2 FLOWER-LAND. 



But look especially at the shape of the corolla. 

 It is something like an open mouth. There are the two 

 lips, and see how prettily the four blackish stamens 

 are arranged under the upper lip which arches over 

 them. There the two lips of the corolla join and 

 form a tube, so that you look through its open mouth 

 into its throat. 



Take hold of the corolla, and pull it. It easily 

 comes away from the plant, and you can see that it is 

 all of one piece or petal. Now look into the little 

 green cup or calyx out of which you have taken the 

 corolla. You will see there four little things which 

 look like seeds. They are really the four little bags 

 or seed vessels of the pistil, about which I have 

 already told you (p. 10). They will ripen into the 

 four little nuts or fruit of the plant, and in each will 

 be one seed. 



The dead nettle is an example of another of those 

 natural orders in which plants are arranged, and 

 about which I am now teaching you. 



All plants with square stems, opposite leaves, fruit 

 of four nuts, and flower of one petal, with two lips> 

 are placed together, and belong to the natural order 

 of the lipped plants. 



Their corollas differ a good 

 deal in the length of the tube 

 or throat, and in the size and 

 shape of the lips ; and I dare 

 say we shall find some other
