 specimen. 



From type 



31. Panicum cayennense Lam. 



Panicum cayennense Lam. Tabl. Encycl. 1:173. 1791. "Cayenna. D. Stoupy." 

 The type, in the Lamarck Herbarium, is labeled "Panicum cayennense Lam. ill. gen. 



aff. Panico capillare." Lamarck states in the 



original description that this species is near P. 



capillare. In the general herbarium at Paris is a 



specimen of P. rudgei from Cayenne collected by 



Le Blond, which is labeled in Lamarck's hand 



"Panicum cayennense lam. illustr. et diet." 



This specimen does not correspond to Lamarck's 



descriptions, especially the later one, a so well as 



does the preceding specimen, which is therefore 



taken as the type. 



Panicum floribundum Rich. ; Lam. Encycl. 4 :742. 



1798. This is given as a synonym under P. cayennense, and credited to "Rich, herb." 



The type, in the Richard Herbarium, is from Cayenne. This specimen agrees with 



the first of those mentioned above. 



Panicum pedunculare Willd.; Steud. Syn. PI. Glum. 1 : 77. 1854. "Brasil." This 

 is credited to " Willd. hrbr." The name occurs earlier & as a nomen nudum. The type, 

 in the Willdenow Herbarium, was collected by Humboldt in " Amer. meridion." 



Panicum cayennense patulum Doell in Mart. Fl. Bras. 2 2 : 220. 1877. Based on P. 

 cayennense Lam. 



description. 



Plants, erect, or, when much-branched at the base, spreading; culms 20 to 50 cm. 

 high, often zigzag, glabrous or more or less papillose-pilose below the pilose nodes; 

 sheaths papillose-pilose, ciliate; blades linear, 10 to 20 cm. long, 4 to 10 mm. wide, 

 rather stiffly ascending, rounded at the scarcely narrowed base, rather sparsely papil- 

 lose-pilose on both surfaces or sometimes nearly glabrous; panicles terminal and 



a Lam. Encycl. 4 : 742. 1798.
