    Distribution

    Anthurium sebastianense is endemic to Ecuador in the Machalilla National Park in the region of San Sebastian, known only from the type locality in the coastal hills near the Pacific Ocean in Manabi Province at 400-700 m in what is probably Premontane moist forest. Although the Holdridge lifezone map of Ecuador (PRONAREG, 1978) maps the locality for the Gentry collection in either Tropical dry forest or Tropical spiny monte the Ceron collection is found in Premontane dry forest. I am assuming that no such species could actually occur in either Tropical dry forest or Tropical spiny monte but that the species is found in this region in an area of regular afternoon cloud forest, making the growth of aroids possible. Thus it is more likely that the region is effectively Premontane moist forest despite the fact that there is no such life zone recognized in this particular region.
