Panicum pubifolium Nash, Bull. Torrey Club 26: 577. 1899. ‘‘P. latifolium var. 
molle Vasey, Contr. U.S. Nat. Herb. 3: 33. 1892. Not P. molle Sw. 1788,” is cited 
and a description follows. As no type is cited this is evidently primarily a change of 
name, based on P. latifolium molle Vasey. 
Panicum boscit molle Hitche.

1a. 359.—P, boscii molle. From type specimen. cent on the upper; panicle axis 
and branches puberulent and 
somewhat pilose; spikelets rather more strongly pubescent than in the species. 
The Florida specimens, together with Biltmore Herbarium 5185b, Dewey 73 and Steele 
in 1896, have spikelets mostly larger than 4.5 mm. long, and correspond with the varia- 
tion of the species which includes P. latifolium australe Vasey.
