False Brome, along the tracks of Dene Park.

False Brome, Brachypodium sylvaticum appears to be quite well distributed across the woodland tracks and paths.

While at first not very sure of it, I was eventually very happy with the identification. It was in the early flowering stage. I could see the spikelets quite round in cross-section, elongated and around 2 cm long. Each spikelet had a very short stalk indeed. The awns were about the same length as the individual flowers, more obvious when I spread the spikelet out.

The nodes and stems were softly hairy, the leaves were bristly (scaberulous, slightly rough to the touch), particularly the underside when rubbed towards the base. They were quite broad but narrowed obviously towards the sheath junction. The ligule was blunt and raggedy, a few mm long. A bright green is how I would describe the leaves, but in the image above it looks relatively glaucous. 

Flowering is stated to be late June onwards. Soils ideally calcareous, not very fertile, well drained. These characteristics seem to fit fairly well.
