The yellow pollen is presented deep within the throat of the flower, reminiscent of Scurvygrasses and Pepperworts, but this plant belongs to the Primrose Family with five petals, not the cabbage (Crucifer) Family with only four.

Many similarities to : Scurvygrasses and Pepperworts belonging to the Cabbage Family (Crucifers), but they have only four petals, not the five of Brookweeds which belong to the Primrose Family.

Distinguishing Feature :

No relation to : Brooklime [a plant with similar name] which belongs to the Speedwell Genus of the Plantain Family, and not of the Primrose Family to which Brookweed belongs.

Enjoys being near the sea and is also found in marshy meadows and damp places near the sea.
