An attractive species that is endemic to southern Mexico…and a stinky one. I can more or less determine its presence in a forest when I first walk into said forest, based on odor in the atmosphere (this also applies to the the other 10 or so taxa in the “bat-loving” Chiropterophila clade). I suspect this species represents an evolutionary “intermediate” in pollination systems (yeah Stebbins…just like you predicted….), i.e., that it is currently adapted to hummingbird pollination but is on its way to full blown bat pollination. Check out that nectary. Some serious fluids flowing from she.
