nodes, the uppermost elongate, scabrous; ligule ciliate, about 2 mm. long; blades

 sometimes as much as 10 cm. or the distant lowermost even longer; spikelets secund 

 on the branches, narrowly ellipsoidal, about 3 mm. long, the pedicels puberulent, 

 usuallj very short, some or all on each branch subtended by somewhat flexuous

 second glume similar to the first, two-thirds the length of the spikelet, 5-nerved;

3. Chaetochloa palmifolia (Willd.) Hitchc. & Chase. 



Panicum plicatum Willd. Enum. PL 1033. 1809. Not Panicum plicatum Lam. 1791. 

 "Habitat in India orien tali. " A specimen in the Willdenow Herbarium in Berlin, 

 cultivated in Calcutta by Roxburgh and sent by him to Willdenow, is probably the 

 type. 



Panicum palmifolium Willd.; Poir. in Lam. Encycl. Suppl. 4: 282. 1816. Poiret 

 states that the native place of this is not known. He cites Panicum plicatum Willd. 

 Enum. PL 2: 1033. 1809, not Lam. Encycl., and quotes the description, adding a 

 description of his own. The locality given by Willdenow is "in India orientali." 

 Poiret says that he saw a specimen in the Desfontaines Herbarium. This specimen 

 was examined in Florence. Panicum palmaefolium Koen. ! may be the same as 

 P. palmifolium or it may be P. plicatum Lam., but it is a nomen nudum, being 

 mentioned in a running account of travels. 



Panicum plicatum haitiense Kunth; Griseb. Fl. Brit. W. Ind. 547. 1864, as synonym 

 of P. palmifolium Poir. This name is credited to Kunth, but the latter appears not 

 to have published it.
