2. Bromus tectorum L. Downy Chess. Map 121. This species is 

 now found throughout the state and has become a pernicious weed in all the 

 northern counties where a sandy soil is found. It is found along roadsides 

 and in waste places, hayfields, pastures, and fallow fields. 



Nat. of Eu. ; throughout the U. S. as far south as Va. and Miss. Common 

 on the Pacific coast. 



3. Bromus inermis Leyss. Smooth Brome. Map 122. I do not know 

 that this species has been intentionally sown to any extent in Indiana but 

 it is now found frequently along railroads and roadsides in sandy soil in the 

 northern half of the state. I found one farmer in Lagrange County who 

 had sown it with success in a field of blow-sand soil. 



Native from central Europe to China; used in the western states as a 

 hay and pasture grass and now found as an escape in the northern half 

 of the United States. 



4. Bromus ciliatus L. Fringed Brome. Map 123. Infrequent in marshes 

 and springy areas of the lake region. I found a specimen in Steuben 

 County with all the sheaths glabrous except the lowest one. This is Bromus 

 ciliatus f. denudatus VViegand (Rhodora 24: 91. 1922) which Fernald 

 now regards as the typical form of the species. (Rhodora 32: 70. 1930.)

5. Bromus latiglumis (Shear) Hitchc. (Bromus altissimus Pursh, 

 Bromus purgans of Britton and Brown, Illus. Flora, ed. 2, and including 

 Bromus incanus (Shear) Hitchc.) Map 124. Infrequent throughout the 

 state. This species seems to prefer dense shade and is found most often on 

 wooded slopes along streams and in ravines, in fact, it is rarely found far 

 distant from a stream. This species was separated from the form with 

 densely pubescent sheaths by most authors but Hitchcock has united the 

 two forms under this name.
