ACOTYLEDONS DIAGRAM 18, 209 



CLASS OF ACOTYLEDONS; 



OR, PLANTS WITH NO COTYLEDON. 



All the plants which still remain to be noticed, and which 

 form the class of Acotyledons, are distinguished from the others, 

 not only because they have no cotyledons, but because the plants 

 themselves have no flowers. They never bear either pistils or 

 stamens. At the proper season, seeds appear at some part of 

 the plant, but do not succeed to flowers. These seeds themselves 

 are most frequently of extraordinary minuteness, so that they 

 resemble dust, like the pollen of coniferse. They are so different 

 from all other seeds that they have received a special name, and 

 are called spores. Some families of the acotyledons still resemble 

 other plants to some extent by their greenness and a kind of 

 foliage, but there are others, such as fungi, which are entirely 

 different from ordinary plants.
