Hackel notes on No. 352 Merrill, that the plant is I'unieuin rctnolnm Retz., 

 and not P. ramosnm Linn., proper, as determined by Mez. Scribner is of the 

 opinion that Panicum miliiforme Presl is a distinct species, but I can find no 

 characters in the description as given by Presl, or in the figure given by Scribner, 

 drawn from Prcsl's type material, by which the species can be distinguished 

 from Panicum remoliim Retz.

Panicum latifolium Linn., is confined to North America, the first reference 

 in Linnaeus' Species Plantarum under the description of the species being to 

 Morison's Hist. PL 3: 196. t. 8. f. '/, a Virginian plant, of which Panicum por- 

 ierianum Nash is a synonym. The second reference given by Linnaeus is to 

 Sloane Hist. Jam. 1: 114. i. 11. f. 3, an entirely different plant of the West 

 Indies, which is Panicum divaricatum Linn. The Asiatic plant referred by 

 Hooker f., to Panicum latifolium Linn., is not at all related to that species and 

 has in my opinion little affinity witli Panicum divaricatum Linn., of the West 

 Indies. As noted by Hooker f., the compressed thickened tips of the empty 

 glumes are very characteristic of the Asiatic form, the Balabac plant closely 

 matching specimens from the Malayan Peninsula.
