+ SPOROBOLUS ASPER (Michx.) Kunth. Mayville, Aug. 21, 
1919: Fargo, Aug. 16, 1920; Steele, Sept. 10, 1920. 
FESTUCA VIRIDULA Vasey. Lunell (Am. Mid. Nat. 4: 224 
1917) has reported this species from Dunseith. I have examined 
carefully a specimen received from him (‘‘det. by U. 5. Dept. 
Agr.’’) but can see no reason why it should not be referred to 
F. Hallii (Vasey) Piper. 
Bromus jJAPonicus Thunb. Fargo, Oct. 1918. Determined 
by Agnes Chase. All of the specimens referred by Bergman to 
B. commutatus Schrad., and several others not reported, seem 
to belong here.

Annual: culms 3 to 4 dm. high, rather a somewhat 
scabrous above; leaves upright, 5 mm. wide, 1 dm more long, 
glabrous or nearly so; glume about three-fourths ; as lide as the 
well developed itkalate equalling the younger or shorter ones; 
spikelets five- to ages habia the larger 2 cm. long; lemmas 
o 10 mm. long bearing an awn 7 to 12 m ng. 
Described from a specimen collected ie 7, 1919, grown 
from seeds found in a sample of wheat from the northeastern 
part of the state. An early maturing annual, not so large as 
L. temulentum L. and quite different in the longer, lanceolate, 
awned florets. The culms commonly bear a branch from the 
first node, some of these in the specimen cited being only 1 dm. 
long with spikes barely protruding. The Milton specimen cited 
by Bergman under L. temulentum belongs here, both it and plants 
from the 1919 culture having been examined by Mrs. Chase. 
The plant seems well established in that vicinity as evidenced 
by these cases, by material received at one or two other times 
and by seeds found in several samples of wheat.

Three species of this genus are of great economic importance 
in North Dakota. Having had occasion to pay particular 
attention to these, I find that as a rule, descriptions and figures 
seem to have been made from immature material, causing certain 
characters to be overlooked. The spikelets are well figured by 
Hillman (Bur. Pl. Ind., U. S. Dept. Agr. Circ. 73. 1911). I 
offer the following descriptions:
