Synonyms[1]
  • Joannesia Pers. 1807, illegitimate homonym not Vell. 1789 (Euphorbiaceae)
  • Joannea Willd. ex Spreng.
  • Diacantha Lag.
  • Johannia Willd.

These are evergreen shrubs. They have many shapes and sizes of leaves, and two general types of flowers apparently adapted for pollination by hummingbirds and insects.[5] Some species occur at elevations over 4000 meters in the Andes, while others can be found at sea level.[6]

Many are of ecological importance because they are dominant plant species in very dry habitat types, and local animals depend on them.[7] Hummingbirds of the genus Oreotrochilus, the hillstars, rely heavily on these plants, and some species have never been observed on any other plant taxa.[8]

Some species have been used as fuel, as traditional medicines, and as ornamental plants.[7]
