Description

''Bromus erectus'' is a perennial, tufted grass with basal tufts of cespitose leaves that is nonrhizomatous. The culms grow between in height. The internodes are typically glabrous. The flattened

Identification

Upright brome can be identified by the "camel's eyelashes", or long hairs, along the edges of the leaves.


Range

Found on well-drained calcerous soils in disturbed areas, fields, and roadsides, ''B. erectus'' is widespread in Europe, South West Asia, North West Africa, and has been introduced into North America.
