Description

Bromus nottowayanus is a perennial grass, lacking rhizomes, with solitary or tufted culms growing up to 0.6–1.5 m (2 ft 0 in–4 ft 11 in) in height. The six to eight cauline leaves have reversed sheaths that are covered with soft hairs. The sheaths nearly cover the nodes and the ligule is hidden. The nodes are either pubescent or glabrous and internodes are glabrous. The grass lacks auricles. The leaf blades are 15–30 cm (5.9–11.8 in) long and 0.6–1.3 cm (0.24–0.51 in) wide and are covered with short hairs on their upper side. The lax and nodding panicle is 5–20 cm (2.0–7.9 in) long and the pulvini are slender. The often recurved branches of the panicle are typically ascending or spreading. The often purplish spikelets have three to eleven flowers and are 1.8–4 cm (0.71–1.57 in) long. The lower glume is one to three-nerved and 5.5–8 mm (0.22–0.31 in) long, and the upper glume is five or seven-nerved and 7–10 mm (0.28–0.39 in) long. The shortly hairy lemmas are 8–13 mm (0.31–0.51 in) long and have straight awns 5–8 mm (0.20–0.31 in) long. The palea is densely hairy and has a flat tip. [1] [2]

The species is distinguished from Bromus pubescens by the satin-like sheen on the underside of its leaves from which it derives its common name. The grass flowers later than B. pubescens as well, flowering in late July rather than late June. [3]

Habitat and distribution

Bromus nottowayanus occurs in shaded hardwood forests, especially near streams, though usually above the lowest and wettest conditions. It occasionally will occur in dryer places. [3]

The grass is native to the eastern and central-eastern United States, from Iowa to New York and south to Oklahoma, and throughout Virginia. [4]

<i>Bromus interruptus</i> Species of flowering plant in the family Poaceae

Bromus interruptus, commonly known as the interrupted brome, is a flowering plant in the grass family. It is endemic to southern and central England, which became extinct in the wild in 1972. After several decades in cultivation, the interrupted brome was re-introduced to Aston Rowant National Nature Reserve in 2004, marking the first known re-introduction of an extinct plant in Britain. The plant was a weed of waste places and arable agriculture, particularly of sainfoin cultivation. It can be distinguished from all other Bromus species by its deeply split, or bifid, palea.

<i>Bromus secalinus</i> Species of grass

Bromus secalinus is a species of bromegrass known as rye brome. The specific epithet secalinus is Latin, meaning "rye-like". The fruits are hard, rounded glumes that appear superficially similar to the rye grain, which gives the brome its common and scientific name. The grass has a diploid number of 28.
