Note. Many species are inserted in this synopsis, as for 

 instance those of Schweinitz, provisionally and approximately, 

 as the intimate structure is too little known to give them a 

 definite position with any degree of certainty. Although 

 these uncertain species are included under definite genera, it 

 must not be supposed that these approximations are given 

 with confidence as to their absolute accuracy.
