MOSSES 



THE PAKTS OV TUK MOSS PLANT 



AVe often hoar people speak of moss as if there were 

 hut one kuuL Perhaps you will be surprised to learn

 like small trees; a number of them resemble feathers. 

 All of them have roots, stems, and leaves, Hke other 

 plants. 



The roots are very delicate, yet they take as firm a 

 hold of the soil, in proportion to their size, as many 

 trees. They consist of small, threadlike fibers, or long, 

 creeping, underground stems, like the ferns except that 

 thev are smaller. In most cases these serve onlv to 

 attach the plant to its growing place, for every part 

 of the moss takes in its own share of nourishment. 



Man}' of the mosses have long stems that branch and 

 brjuich again. Others have scarcely an\' stem. Thev 

 seem to send up from the root a mere tuft of leaves. 

 The stems are solid and are made up of many cells. 

 They have no woody fibers running through them as the 

 ferns and flowering plants have, so they cannot stand 

 up erect. These stems are of a reddish color, or of 

 green or brown. If you look at a moss stem carefully 

 you will find that the leaves grow around it on all sides.
