103. Panicum nitidum Lam. 



Panicum nitidum Lam. Tabl. Encycl. 1 : 172. 1791. "E Carolina, com. D. fraser." 

 The type, a in the Lamarck Herbarium, consists of a panicle and the uppermost 

 joint of the culm with its leaf, the blade renexed, the node sparsely clothed with 

 reflexed hairs. This specimen does not belong to any of the species to which the 

 name P. nitidum has been applied by American authors. 



Panicum nodiflorum Lam. Encycl. 4: 744. 1798. Lamarck states as to the origin 

 of his specimen, "J'en possede un exemplaire recueilli par M. Fraser dans la Caroline. 

 Le citoyen Michaux l'a trouvee dans la Basse-Caroline." The type, in the Lamarck 

 Herbarium, is a fragment of an autumnal culm with two nodes, at each of which is 

 a fascicle of branchlets with reduced leaves but devoid of spikelets. It is from 

 "Caroline." 



Panicum dichotomum nitidum Wood, Class-book ed. 3. 786. 1861. This is presum- 

 ably based on P. nitidum Lam., though no synonym nor locality is cited. The short 

 description seems to apply best to P. lindheimeri Nash. 



Panicum subbarbulatum Scribn. & Merr. U. S. Dept. Agr. Div. Agrost. Circ. 29: 

 9. 1901. Based on "(Panicum barbulatum of Ell. Sk. Bot. S. C. and Ga. 1 : 127. 1817, 

 notMichx. Fl. Bor. Am. 1 : 49. 1803.)" "The type of the species in the herbarium 

 of Elliott" consists of three vernal culms lacking the base.
