Summary of Differences in the Saretha and Sunnabile groups. 



The summary of differences, noted in the characters of the Saretlia and 

 Sunnabile groups of indigenous Indian canes, has been drawn up in tabular 

 form. By this means a great deal of repetition is avoided, the statement 

 aains in clearness and the various measurements can be more readily compared. 

 In all cases, a fuller study is made in the detailed list given further on, and 

 reference to it is invited to clear up doubtful points. Mention has been made
