Several optical tests were employed to demonstrate twinning in raphides from 10 species in the family Vitaceae and one species in the Araceae. Scanning electron microscopy revealed that twin raphides differ from the reported shape of twin styloids and that raphides of the Vitaceae are "barbed" along two sides. A model is proposed to describe in vivo raphide production under saturated to supersaturated conditions of directional nutrient flow.
