Small Crab-grass. Digitaria humifusa Pers. (Panicum lineare Krock. Syntherisma 

 linearis (Krock.) Nash.) A smooth, slender annual with stems usually prostrate, 

 spreading, 15-35 cm. high, each stem bearing 2-6 slender one-sided spikes. Whole 

 plant of a reddish hue, not rooting at the nodes. Common in thin lawns and pastures 

 late in the summer. Unless crowded the stems are prostrate. Introduced from 

 Europe. 



If lawns and meadows are enriched, the better grasses and clovers will crowd this 

 plant out.
