small coastal flower

[Naturenutz]

The flowers on this plant were very small 5mm or so.They were a few of these growing along a coastal path near the river severn in south gloucestershire.
Any ideas please

[Hedera]

I think this may be Sea spurrey, maybe Greater - Spergularia media.

1. Greater Sea-spurry - Spergularia media. Petals longer than sepals. Fruiting stalks shorter or equaling fruit. Leaves more greeny-yellow than 2.

2. Lesser Sea-spurry - Spergularia marina. Petals usually shorter than sepals. Fruiting stalks longer than fruit.

Therefore I go for 1. Greater Sea-spurry.
