Leafy Mosses 



sufficiently strong to permit their leaf-green to manufacture plant 

 food. 



THE HAIRY-CAP MOSSES 



Among the best subjects for a beginner are the 

 Hairy-caps, the most common mosses, which every- 

 one who frequents the woods will find bordering 

 trails and wood-roads, or covering the ground in

almost all open places. They are so large that with 

 a hand-glass many of the principal parts may be made 

 out and will thus serve as a foundation for a study of 

 other mosses. 



FRUITING PORTION (SPOROPHYTE). 



The most striking part of the plant (Gametophyte) is 

 the fruiting portion (sporopliyte) with its parts. The 

 spore-case is a thin-walled cylindrical box with 

 four or six sharp edges running lengthwise. The 

 spore-case is borne on a 

 flexible pedicel (seta), the sporf- 



two together resembling a apophysts 

 tiny Turkish pipe. In cer- 

 tain stages of this moss the 

 spore-case is entirely 

 covered with a conical
