Bromus confines is similar to and intergrades with Bromus inermis, differing mainly by the combination of long awn, hairy spikelets and pubescent sheaths and blades. The inflorescence is typically racemose and rather dense, grading into a long-branched form corresponding to
Bromus munroi, which is here considered conspecific with
Bromus confinis. Like
Bromus inermis, Bromus confines is also part of a species complex and is not very well distinguished from either
Bromus inermis or the northern Asian
Bromus sibiricus. The latter is found from Northwest Russia across to East Sibiria and Mongolia and differs from
Bromus confines by the lemmas being hairy only on the marginal nerves. It should perhaps be sought in Kashmir where it may conceiveably occur.
Specimen Hans Hartmann 75 has previously been determinated as Bromus biebersteinii Roem. & Schult. (see Stewart, Ann. Cat. Vasc. Pl. W. Pak. 139) but its hairy spikelets and green (rather than glaucous) leaves preclude such a possibility. It fits better in Bromus confines although it is an otherwise glabrous plant.
Bromus confines is found mainly at high altitudes.
