Panicum mattamuske[e]tense Ashe, Journ. Elisha Mitchell Soc. 15:45. 1898. 
“Roadsides, ditch banks, and wet open woods around Lake Mattamuskeet, N.C. 
* * * Collected by the writer, and Mr, Gilbert Pearson in June, 1898.’’ The type 
could not be found in Ashe’s herbarium, In the National Herbarium is a specimen 
labeled ‘‘Panicum Mattamusketense Ashe, Lake Mattamuskeet” in Ashe’s hand- 
writing, collected ‘June 10-July 6, 1898,” by ““W. W. Ashe,” evidently a duplicate 
type. This is a single vernal culm nearly 80 cm. high, with a mature panicle, and 
agrees in all respects with the description except that the spikelets are described as 
glabrous, while those of the specimen are pubescent. The two lower sheaths and 
lowest blade are velvety pilose; the spikelets are 2.3 mm. long. A second duplicate 
type in Biltmore Herbarium is a better and more characteristic specimen.
