Bull. 5: 21. 1897, not P. brevifolium L. 1753. ‘Montana: Manhattan, on a shaded 
sandbar in the Gallatin River; July 19, [Shear] 436.” The type, collected by C. L. 
Shear, is in the National Herbarium. 
Panicum barbipulvinatum Nash in Rydb. Mem. N. Y. Bot. Gard. 1: 21. 1900, ‘“Pani-

The specimen, in the herbarium of the New York 
Botanical Garden, agrees with Shear’s no. 436, men- 
tioned above.
