43. DACTYLOCTENIUM Willd. 



One species of this geims was introduced from the warmer parts of 

 the Old World and is found in the southern part of the state. Both in 

 habit and in general appearance it is somewhat like Eleusine indica, 

 having spikes arranged in the same manner (Fig. 201). It may readily 

 be distinguished by the prolonged rachis which forms a point beyond 

 the spikelets. The spikelets are flattened, 3- to 5-flowered, sessile. The 

 glumes are broad and keeled, the lemmas sharply pointd. The leaves 

 are flat and narrow.

Culms 6 inches to 2 feet tall, usually spreading and rooting at the
