Fic. 278.—Distribution of P. polyanthes. 
151. Panicum erectifolium Nash. 
Panicum sphaerocarpon floridanum Vasey, U.S. Dept. Agr. Div. Bot. Bull. 8:33. 
1889, not P. floridanum Trin, 1835. “Florida.’’ Inthe National Herbarium are three 
specimens from Florida marked in Dr, Vasey’s writing ‘‘ Panicum sphaerocarpon Ell. 
var. Floridanum.’’ Of these Curtiss 3599, from ‘‘ Moist pine barrens, Mosquito Inlet, 
Florida, May, 1879,”” has been chosen as the type, since with the other two no locality 
within the State is given. This specimen consists of two plants 45 and 50 em. high, 
with mature panicles of densely puberulent spikelets. 
Panicum erectifolium Nash, Bull. Torrey Club 28: 148. 1896. Based on P. 
sphaerocarpon floridanum Vasey, not P. floridanum Trin. 
Panicum floridanum Chapm. Fl, South. U. 8. ed. 3. 585. 1897, not Trin. 1835. 
“Tn and around shallow ponds, near the coast of West Florida.’’ The type, in the 
Chapman Herbarium at Biltmore, is from Apalachicola. Chapman presumably 
intended to base his name upon P. sphaerocarpon floridanum Vasey, but cites ‘‘(P. 
macrocarpon, var., Vasey. 1. sphaerocar pum, Flora.)”’
