APPENDIX. 



A TABLE OF THE CRYPTOGAMIA, OR 

 FLOWERLESS PLANTS. 



IT may be objected that in the foregoing pages there is no 

 systematic treatment of the various groups of flowerless 

 plants. This is intentional. We have briefly alluded to 

 ail the orders of cryptogams, but have entirely ignored 

 the position of these orders in scientific classification. For 

 instance, we have grouped together what are popularly 

 known under the general term of Mosses, although some 

 are widely separated from the others in classification. Our 

 reason for doing so is the fact that this book is intended 

 for the non-scientific reader. For the benefit of those 

 who wish to ascertain the proper relation of these orders 

 to each other, we append a table of the classification of 

 these plants.
