Ireland

Compact Rush

Juncus conglomeratus

Common in wet grassland and moorland, in similar habitats to Soft Rush

Flowerhead diameter c 8-10 mm, more in occasional lax-flowered specimens

ID: Similar to Soft Rush, but stems clearly ridged (ridges can be felt with fingers).

Other features: Normally shorter than Soft Rush, flowerheads usually compact.  I have occasionally found very robust forms which I suspected to be hybrids but they turned out to be the species.  Hybrids with Soft Rush probably do occur here, however.
