Drop-seed grass. — Generic name for species of Sporobohis; also 

 applied to species of Muhlenbergia (e. g. Sporobohis com- 

 pressus^ Muhlenbergia Jfexicana.)

East Indian Millet. — Pennisetuin spicatu?n, 



Eaton's grass. — Eatonia Pennsyhanica. 



Eatonia obtusata, Gray. — Early Bunch-grass, Prairie-grass. 



A form of this grass is reported by Gattinger as occurring in 

 the ''Highlands." We do not know that it has any agricultural 

 merits. 



Eatonia Pennsylvanica, Gray. — Eaton's grass. 



This is a native species which we have occasionally seen grow- 

 ing here in moist meadows. It is usually of a paler green than 

 other grasses, and stands out conspicuously among them on this 

 account. It grows to the height of two or three feet, and has a 

 rather long and narrow panicle. There is another species of 

 Eatona {E. Dudley i) which is common in our woods, blo(5ming in 

 April or early in May. Its stems are much more slender than 

 those in the other species, and its leaves are shorter, being 

 rarely more than two or three inches long. Of no agricultural 

 value. 



Egyptian-grass — Sorghum Halapense. 



Egyptian Millet. — Pennisetum spicafum, Sorghum Halapense. 



Eleusine Indica, Gcertn. — Goose-grass, Dog's-tail grass. Yard -grass, 

 Crow-foot-grass, Wire-grass, Crab -grass. Crop-grass, Dog's- 

 tooth grass, Buzzard-grass. 

 This is an exceedingly common annual growing in dooryards 

 and cultivated grounds, particularly in rich soils. The stems 

 are somewhat flattened, many springing from a single root, and 

 each terminated by two to several spikes, which stand out like 

 the fingers of a hand or the toes of a crow's foot. 



Crow-foot grass, or yard-grass, are the names which are usu- 

 ally applied to this species. It is only rarely called crab-grass, 

 which name really belongs to Panlcum sanguinale. Some authors 

 . liave spoken of it as being nutritious, and good for grazing or 

 soiling and for hay, but we have always regarded it as a weed, 

 and sometimes a troublesome one.
