 terminal spikes, and the stipitate flowers and fruit enclosed in a flat 

 or triquetrous scale which exceeds the glumes, and the absence of 

 setse. The species here noted is a small, slender plant 15-20 cm. 

 high, with the narrowly linear leaves crowded at the base and 

 shorter than the culms. Spikes closely crowded. in a globose or 

 ovoid head, 7-10 cm. long, subtended by 2 spreading bracts much 

 longer than the head. Scale compressed, broadly and niembra- 

 nously winged, tipped with an awn about one-third of its length. 

 Nutlet dark, oblong, slightly angled on one side, tipped with the 

 remains of the style, 1 mm. long. 



This little plant, with its small white heads, dots the grass lands 

 about Asuncion and Villa Rica in large numbers.
