14 THE SEEDS OF THE BLUEGRASSES. 
Prof. L. R. Jones, of the Vermont Agricultural Experiment Station, 
reports the seed production from a nearly pure stand of this grass as 
amounting to 6 bushels of 19 pounds each per acre. A small plat 
yielded seed at the rate of over 7 bushels per acre. The seed is pro- 
duced abundantly and ripens evenly. In Vermont it is harvested in 
the latter part of July. The name fowl meadow grass is often applied 
to another lowland grass, Panicularva nervata. 
Poa arachnifera (Texas bluegrass).—The seed of Texas lice is 
gathered by hand in northern Texas. It is cleaned by rubbing 
between the hands, and, owing to the long, woolly hairs at the base of 
the seed, it is never ‘‘ fancy clean.” The best seed is produced on 
rich, black, waxy soil, and is ripe about May 1 to 15. Only a small 
quantity is gathered each year, and consequently it is high priced and 
can not be considered as a commercial seed at the present time. 
Poa annua (annual bluegrass).—The seed of the annual bluegrass is 
not on the market in this country, though the plant is common about 
dwellings, especially in the South and East, and ripens its seed 
throughout the summer. The seeds do not ripen evenly, the upper 
ones falling before the lower flowers have opened. The seed is 
gathered and used to some extent in Europe. 
Poa alpina (alpine meadow grass).—Alpine meadow grass is best 
known in Switzerland, where the seed ripens from the end of June to 
the middle of July. The viviparous form can be propagated by scat- 
tering the buds during the hot weather. 
Poa sudetica.—The seed of Poa sudetica, which is a Kuropean grass, 
is rare in the market, but is occasionally quoted by French and by 
German firms. It is sometimes mixed to some extent with the seeds 
of the meadow grasses, particularly water meadow grass (Panicularia 
americana). 
In addition to the foregoing, other species of Poa occur in the 
western and northwestern United States, where they contribute to 
the native forage of the stock ranges. The seeds of these species, 
however, are not found in commerce.
