In this variety, as in most of C. cruentus ty])e, the spikelets as they ripen get 

 very brown; in C. conglomeratus they usually remain pallid. In a given length of 

 rhachilla there are neaVly twice as many nuts in C. cruentus as there are in C. con- 

 glomeratus. 



21. C. effasus, Rotth. Descr. et Ic. 22, t. 12, fig. 3. Stem rather 

 stouter, striate, terete, hardly at all trigonous even at the top. Spikelets 

 nearly as those of C. cruentus, i.e. narrower with less distant glumes 

 than the spikelets of C. conglomeratus, otherwise as the two la.st species.
