Steudel records this from Panama, but probably in error, for Humboldt and Bonpland’s 
original habitat is “‘Insula Orinocensis Panumana, inter vicos Atures et San Borja.”

We have not succeeded in ascertaining what the North-American botanists have done 
with Torrey’s plant, therefore we can merely copy Fournier.

_ We have not identified anything in the Kew Herbarium with this. Panicum pauci- 
Joorum, Elliott, appears not to be known with certainty by American botanists, for Gray 
(Man. Bot. Northern U. S. ed. 5, p. 648) places a note of interrogation after the name, 
and states that the plant which he describes has probably been described under several 
names ; and Chapman (FI. Southern U.S. p. 575) copies Elliott’s description. Panicum 
umbrosum, Leconte, is probably a nomen nudum, though this point we cannot determine as 
we have not seen Leconte’s catalogue ; but Torrey (Flora of New York, i. Preface, p. 2), 
who specially mentions Leconte’s Catalogue, does not take up the name. Fournier, 
however, places the sign of certainty after both names. Steudel, in his ‘ Nomenclator, 
cites P. umbrosum, Leconte, as a synonym of P. verrucosum of Miihlenberg.
