HITCHCOCK REVISIONS OF NORTH AMERICAN GRASSES. 159 



As usual with annuals, this species varies greatly in the size of the plants. Vigorous 

 plants may have numerous culms as much as 2 meters long, with correspondingly large 

 blades and panicles; dwarf plants may be only 10 cm. tall, with obscurely plicate 

 blades and few-flowered spikelike panicles.

 elongatum Salisb. 1796, nor Pursh, 1814. "Cette plante croitau Bresil (V. s. in herb. 

 Desfont.). " The type, in the Desfontaines Herbarium at Florence, consists of a 

 portion of a blade and a nearly complete panicle. 



Panicum sulcatum Bertol. Excerp. 14. 1820. Not Panicum sulcatum Aubl. This 

 citation has not been verified. The species is said to be from Brazil and apparently 

 is described independently of P. sulcatum Aubl.
