Bromus secalinus is a species of

diploid number
of 28.

The grass is native to Eurasia but is well known in many other parts of the world where it has been introduced. It is a noxious weed throughout much of North America.

Description

Bromus secalinus is an annual grass that grows 0.1–1.3 m (4 in – 4 ft 3 in) high. The upper sheaths are smooth and strongly nerved, and the lower sheaths are glabrous or slightly pubescent. The leaf blades are 15–30 cm (6–12 in) long and 2–4 mm (0.1–0.2 in) wide, and are covered with short hairs. The

anthers are 1.5–1.8 mm (0.1–0.1 in) long. The caryopses are thick and strongly inrolled when mature.[3][4]

The grass flowers from June to September.

In youth the two

brome grasses Bromus secalinus and Bromus arvensis are very similar, but are easily distinguishable in maturity. Bromus arvensis has fully pubescent leaves but Bromus secalinus lacks trichomes on the undersides of leaves.[5]

Habitat and distribution

Bromus secalinus occurs in fields areas, road verges, and occasionally cornfields, in lightly stony soils.[5]

The grass is native to Europe but is widespread throughout the United States and in Quebec and British Columbia.[4]
