from mosses in dry air ? Does the moss have a well-developed 

 transportation system for water, similar to the fibrovascular 

 bundles of higher plants, which would be capable of trans- 

 porting water for a large leaf area? Upon the basis of these 

 facts, can you account for the restriction of the mosses, com- 

 monly, to locations with moist soil and moist air. Do you 

 consider them to be more, or less, well fitted to grow upon land 

 than the algse ? than the flowering plants ?
