Drosophyllum (/ˌdrɒsɵˈfɪləm/, rarely /drəˈsɒfɪləm/) is a genus of carnivorous plants containing the single species Drosophyllum lusitanicum (Portuguese sundew or dewy pine). In appearance, it is similar to the related genus Drosera (the sundews), and to the much more distantly related Byblis (the rainbow plants).
