Mudwort - Limosella aquatica

A low, hairless plant with creeping and rooting runners. Leaves in basal clusters, linear oblong to elliptical, often broader above the middle, untoothed and rather fleshy. Flowers white, often marked with pink, 3 mm, bell shaped, 5 lobed, solitary.

Records from this species should be confirmed by a County Recorder for botany.  It is on the VC55 Rare Plant Register, and therefore a specimen should not be taken.  Take detailed field photos and submit to NatureSpot as soon as possible; and if you think you have found it in a new location, inform the County Recorder as soon you can.
