Heath False-brome agg. - Brachypodium pinnatum agg.
A tufted grass to 120 cm, which is almost hairless, spreading by creeping, wiry rhizomes. The leaves are usually under 5 mm wide, often with inrolled edges and with very short ligules. Spikelets sessile, alternating, with short awns. The only reliable distinction between B. rupestre and B. pinnatum is the presence of minute prickle hairs (<30 um) on the veins of the lower surface for this reason we have decided to treat them as an aggregate.
Flowering in July.
Local in southern and south eastern England north to Yorkshire, quite scarce elsewhere in Britain.
Local in Leicestershire and Rutland where it is found mainly on the Oolite Limestone. In the 1979 Flora survey of Leicestershire it was found in 71 of the 617 tetrads.
