LIFE-HISTORIES 



In dry weather, after calyptra and lid have fallen, a strong wind 

 will shake the capsule on its slender elastic foot-stalk, and scatter 

 the spores out between the teeth. The most remarkable difference 

 between the sporo]ihytes of Funaria and Sphagnum is that the 

 former like tliat of Anthoceros contains chlorophyll and is thus able

 the sporophytes of Riccia and I\'Iarchantia in being entirely para- 

 sitic upon the gametophyte. Inorganic materials absorbed" by the 

 slender pseudo-roots of the gametophyte are supplied to the foot 

 of the stalk and thence conducted to the photosynthetic tissue of 

 the capsule. Conduction take places mainly through a ccntrnl
