 duae pedunculum bractea spathacea vaginatiun terminantes. Rachis articulata, glabra: nodi breviter ac 

 parce pilosi. Spicules geminae, glabrae ; altera pedicellata neutra, lanceolata, striata, mutica ; altera sessilis, 

 hermaphrodita, uniflora, glumis striatis, glumella exteriore aristata ; arista flosculum subsequans, medio geni- 

 culata, interne tortilis. 



We bave not been able to refer this species to any described one. It approaches much to A. hirtus of 

 the South of Europe, but differs from that and from almost every hitherto known species of the genus, by 

 the nearly total absence of hairs on the rachis ; these, indeed, are so short and so few as to leave some doubts 

 if it ought to be retained in Andropogon, although agreeiug well in other points with the reformed character 

 as given by Trinius.
