Saltmarsh Starwort

Stellaria humifusa Rottb.

Comments

provided by eFloras
Stellaria humifusa is often confused with S. crassifolia, but has thicker stems and fleshy leaves that wrinkle and tend to turn brownish when dried. Also, in S. crassifolia the long pedicels are very slender and sharply angled below the capsule.
