Caryophyllaceae: Pink Family — Catchfly & Pink
In the Pink family, leaves are generally opposite on swollen nodes. Most genera have smallish, regular, 5-petaled and 5-sepaled flowers. Silene (Catchfly or Campion) has larger, more striking flowers. A few genera, such Herniaria (Rupturewort) and Cardionema (Sandmat), have petal-like sepals, but lack true petals.
