Festuca elatior and F. hclerophylla. 
Both of these grasses are natives of Europe and are grown as 
hay and pasture grasses. The tall meadow Fescue is a coarse 
growing grass. The young seedlings appeared above the soil in 
about twelve days after the seed was sown. They grew vigor¬ 
ously, becoming rather broad leaved and coarse. 
The seedlings of the various leaved Fescue were a little 
darker green in color than those of F. elatior. They were also 
a little longer in appearing above the soil, about two weeks 
elapsing after the seed was sown before they appeared. 
Spores from rye were sown on both of these grasses while 
spores from blue grass were sown on F. elatior only. No in¬ 
fection occurred. 
Dactylis giornerata. 
Orchard grass is grown quite extensively for forage purposes. 
It has the habit of growing in tufts. It is easy to work with as 
the seedlings grow vigorously and rapidly. They appear in 
two weeks after sowing. The mildew has not been reported 
upon the grass in this country. Spores from neither rye nor 
blue grass were able to infect it. 
Phleum pratense. 
Timothy is a native of Europe, but was naturalized in Amer¬ 
ica many years ago. It ranks in this country as by far the 
most important of hay grasses and it is certainly commonly 
associated with the grains. The seed germinates quickly, the 
young seedlings appearing in about nine days. The seedlings 
grow rapidly and are very hardy. No infection occurred from 
inoculation with spores from either rye or blue grass. 
Glycena fluHans. 
Floating meadow grass is found in wet soils and marshes and 
its damp surroundings should favor the mildew. The young 
seedlings appear above the soil in ten days. They grow very 
rapidly becoming quite tall and slender. Only spores from rye 
were tried on the seedlings of this grass. No infection resulted.
