Panicum wilmingtonense Ashe, Journ. Elisha Mitchell Soc. 16: 86.1900. ‘‘The 
type material collected in May, 1899, on the sand hills near Wilmington, N. C., is 
preserved in my herbarium.’”’ The type, in Ashe’s herbarium, is labeled, “‘Shady 
slopes on the sand hills one mile to north of Wilmington, May 17, 1899. W. W. Ashe, 
Collector.’? The plants are the vernal form with some autumnal culms of the preced- 
ing season attached.

1854. ‘‘Auburn, Ala., May 7, 1898. Number 1530, Alabama Biological Survey.” 
The type, in Ashe’s herbarium, is a tuft of young vernal culms, the panicles only 
partly exserted. Mounted on the sheet with this is 
a specimen of P. lucidum. Ashe’s description refers 
to the latter only in so far as the spikelets are said 
to be glabrous.
