Hackel notes on No. 352 Merrill, that the plant is Panicum remotum Retz., 
and not P. ramosuvi Linn., proper, as determined by INIez. Scribner is of the 
opinion that Panicum nriliifornw Presl is a distinct species, but I can find no 
chai'acters in the desci'iption as given by Presl, or in the figure given by Scribner, 
drawn from Presl’s type material, by which the species can be distinguished 
from Panicum remotum 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 HisL PI. 3 : 190. t. 8. f. 4, Virginian plant, of which Panicum por- 
ierianU7ii Nash is a synonym. The second reference given by Linnaeus is to 
Sloane Hist. Jam. 1 : 114. t. 71. f. 3, an entirely difl'erent 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 with 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.
