(1) Section of sheathed leaves circular or nearly so, the 
shoots being only slightly compressed. 
* Perennial. 
Bromus inernis (Awnless Brome). 
Sections circular, the leaves being convolute, base 
shelving. Glabrous sheaths and leaves. Stoloniferous. 
Ligule short, truncate, and finely toothed. A forage grass 
of the Hungarian steppes. Now being grown in this 
country, but of doubtful value here. 
Bromus erectus, Huds. (Upright Brome). A weed. 
Sections oval and rounded, but leaves equitant. Radical 
leaves remain folded and almost subulate, hairy edges. No 
stolons, Fields, &c. It is a weed on dry lands, and of 
little or no value. 
Bromus asper, Murr. (Hairy Brome). In thickets, &c.: 
a weed, and useless. Leaves green, long, flat, hanging, 
and eared. Sheath with scattered deflexed hairs. Lamina 
tapering at the base. Keel a white line, ridges incon- 
spicuous: distance between veins 2—3 times breadth of 
latter. Ligule very short, toothed. 
B. giganteus, L. (Tall Brome), also comes here. It is 
less common and glabrous. Woods, Wc., a useless weed. 
** Annual or biennial. 
Bromus mollis (B. arvensis, var. mollis, L.), Field 
Brome. A too abundant and useless weed in water- 
meadows and hay-fields. Softly downy. Blades very thin 
and not eared: dry. 
Bromus sterilis, L. (Barren Brome). A useless weed. 
Rough and downy, but less so than the last. Moist way- 
sides, &c.
