NEW OR NOTEWORTHY GRASSES^ 
A. S. Hitchcock 
In a recent revision of the specimens of grasses from the United 
States in the U. S. National Herbarium, the following notes that 
seemed worthy of record were made. 
Manisuris L. Mant. PI. 2: 300. 1771. Rottboellia L. f. Nov. Gram. 
23- 1779- Hemarthria R. Br. Prodr. Fl. Nov. Holl. 207. 1810. 
Coelorhachis Brogn. in Duperrey, Bot. Voy. Coquille 64. 1831. 
Stegosia Lour. Fl. Cochinch. 51. 1790. 
We are considering these groups congeneric under the oldest name. 
Manisuris fasciculata (Lam.). Rottboellia fasciculata Lam. Tabl. 
Encycl. i : 204. 1791. Hemarthria fasciculata Kunth, Rev. Gram, 
i: 153. 1829. 
Rytilix granularis (L.) Skeels, U. S. Dept. Agr. Bur. PL Ind. Bull. 
282: 20. 1913. Cenchrus granularis L. Mant. PI. 2: 575. 1771. 
Skeels has vshown that the earliest generic name for this species, 
hitherto referred to Manisuris and to Hackelochloa, is Rytilix Raf. 
Andropogon stolonifer (Nash). Schizachyrium stoloniferum Nash in 
Small, Fl. Southeast. U. S. 59. 1903. 
HoLCus Sorghum L. Sp. PI. 1047. 1753. 
HOLCUS HALEPENSIS L. loc. cit. 
Elsewhere^ have been indicated the reasons for using the name 
Holcus for the group of plants including the sorghums and Johnson 
grass. Holcus sorghum is the type of the genus Holcus. The grasses 
that have been included by recent authors under Holcus have received 
a new generic name Notholcus Nash.^ 
Chaetochloa lutescens (Weigel) Stuntz, U. S. Dept. Agr. Bur. PI. 
Ind. Inv. Seeds 31: 36. 1914. Panicum lutescens Weigel, Obs. 
Bot. 20. 1772.
