Stems hairless or with inconspicuous fine hairs in two lines running down from the leaf-bases. Lower leaves opposite each other, those in the flowering region alternating along the stems, rather crowded, 0.5–2 cm long, 2–5 mm wide, glossy, usually with 3-5 shallow gland-tipped teeth. Flowers with 4 deeply notched white petals 3–5 mm long, and a hairless floral tube. Flowers single. Flowering: summer.
