Heath False-brome agg. - Brachypodium pinnatum agg.

    Description

    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.
