These melicopes are part of the m. volcanica complex - m. volcanica, m. radiata and m. pseudoanisata. They are fairly widespread, though not as abundant as melicope clusiifolia. I am not sure if I can differentiate m. radiata from m. volcanica. M. pseudoanisata is supposed to have a strong anise odor, which none of the plants in this subgallery did. Vague fresh citrusy scent is most common.
