 ? Panicum echinatumWilld., Enum.PL 1032. 

 1809. "America meridionali." Wiegand 

 (Rhodora 23: 60. 1921) takes up this 

 name for Echinochloa crus-pavonis. The 

 specimen in the Willdenow Herbarium 

 named P. echinatum (Magdalena, Co- 

 lombia, Humboldt) is Pseudechinolaena 

 polystachya (H. B. K.) Stapf. The brief 

 description does not apply to the speci- 

 men so named nor to E. crus-pavonis. 

 Willdenow differentiates the species 

 from P. crusgalli (with "glumis aristatis 

 hispidis") by "glumis aristatus muri- 

 cato-echinatus," whereas in E. crus-pa- 

 vonis the glumes are less muricate than 

 in E. crusgalli. 



Setaria muricata Beauv., Ess. Agrost. 51,
