      Similar :

      Etymology :
      The genus Allamanda is named after Jean Allamand, an 18th century Dutch naturalist who is a specialist in the flora of Brazil. 
      The specific epithet oenotheraefolia comes from Oenothera which is a group of plants collectively known as evening primrose, and folium meaning leaf, which refers to the similarity of Allamanda foliage to the evening primrose.
