Spiked Sedge (Not Star Sedge, I'm fairly sure)
Observation - Spiked Sedge (Not Star Sedge, I'm fairly sure). Description:
Densely tufted sedge growing in damp, neutral grassland on the London Clay. All the features (see below) point to Spiked Sedge rather than Star Sedge. Also, see the other photos of the glumes etc. close up and against a ruler to show size.
