Equal in size to the large forms of C. rotundus, but has slenderer rays and 

 spikelets. It is C. tuberosus of herbs of Koenig, Rottler and Roxburgh ■ the figure of 

 Rottboel (tuberosus) does not agree very well ; but, as it is satisfactory to Boeckeler, 

 and as it is impossible to identify an old picture without analyses, it saves complica- 

 tion to accept his identification, rather than to separate further the C tuberosus of 

 Bottler (and others) from that of Rottboell.
