151. Panicum erectifolium Nash. 



Fig. 278.— Distribution of P. polyanthes. 



Panicum sphaerocarpon floridanum Vasey, U. S. Dept. Agr. Div. Bot. Bull. 8: 33. 

 1889, not P. jloridanum Trin. 1835. "Florida." In the 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 cm. high, 

 with mature panicles of densely puberulent spikelets. 



Panicum erectifolium Nash, Bull. Torrey Club 23 : 148. 1896. Based on P. 

 sphaerocarpon floridanum Vasey, not P. floridanum Trin. 



Panicum floridanum Chapm. Fl. South. U. S. ed. 3. 585. 1897, not Trin. 1835. 

 "In 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. 

 microcarpon, var., Vasey. P. sphaerocarpum, Flora.)"
