Odontonema cuspidatum (Nees) Kuntze, a veritable plague in parts of the Rio Abajo fores but also a hummingbird magnet

Very common in certain parts of the Rio Abajo forest.  I have seen it mainly growing in roadsides.  Hummingbirds are attracted to the flowers, when a patch of this plant has many inflorescences open it almost sure that you will see hummingbird visit the flowers.
