form (P. Arnotlianum Necs) most common in European herbaria. Kunth's 

 Panicum nodosum was, however, based on Presl's Panicum multinode, the type 

 being from Luzon, and moreover both Presl's and Kunth's diagnoses apply 

 to the Philippine material cited above. I am of the opinion that Haenke's 

 Luzon plant, the type of P. nodosum is identical with the material cited above 

 and with Balansa's Cochin China material, and that therefore to this form belongs 

 the name Panicum nodosum typicum, and to the Indian plant the name P. Arnot- 

 tianum as a species or variety.
