DOUBTFUL SPECIES. 



Panicum echinatum Willd. Enum. PL 1032. 1809. " Panicum muricatumHomem . 

 Cat. hort. haf . p. 28 * * * Non est P. muricatum Retzii." " Habitat in America 

 meridionali." The type has not been examined, and the brief diagnosis is insufficient 

 for identification. In Hornemann's catalogue the name is ascribed to Retzius, and 

 there is no description. 



Oplismenus echinatus Kunth, Rev. Gram. 1: 45. 1829. Based on " Panicum 

 echinatum Willd."
