Formal Taxonomy

Plantae - Anthophyta - Monocotyledoneae - Cyperales - Poaceae - Bromus - Treated in most older floras as native to Europe, however, if the w. U.S./Canada native B. pumpellianus is included as a subspecies of B. inermis (as in Kartesz 1994), the full species is considered native to these countries as well. Kartesz 1999 includes 'pumpellianus' in Bromus inermis as a subspecies, as well as two varieties of B. inermis ssp. pumpellianus (B. inermis ssp. pumpellianus var. arcticus and B. inermis ssp. pumpellianus var. pumpellianus). Subspecies pumpellianus and its varieties are considered native to North America while the other subspecies of Bromus inermis, B. inermis ssp. inermis is non-native.

Ecology and Life History

Short General Description

Bromus inermis is a deeply rooting, rhizomatous perennial grass.

Reproduction Comments

condition in which shoot density is reduced and symptoms of nitrogen deficiency are exhibited (Meyers and Anderson 1942). Benedict (1941) attributes this condition to a carbon/nitrogen imbalance (perhaps because of the sheer mass of dead rhizomes) but Grant and Sallans (1964) suggest that the decomposing roots may actually produce an allelopathic substance inhibitory to further brome root development.

Global Range

Within the United States smooth brome has been introduced in the northeastern and northern Great Plains states as far south as Tennessee, New Mexico and California. It has become naturalized from the maritime provinces to the Pacific coast north to Alaska to California and through the plains states.
