A species of Bromus described by me in 1976. Age not permitting I could not climb those difficult slopes when I visited the area last year, as such I am uploading the isotype.
 
Named after the peak Barobal avove Harwan in Kashmir, the species looks similar to B. japonicus but easily differentiated by its larger spikelets being compressed and solotary at apices of hairy flexuous branches of panicle, glumes and lemma hairy and anthers larger. I am reproducing from original publication.
