    此地點的物種說明:
    Cestrum nocturnum is noted as prevalent and invasive on Rarotonga by Space & Flynn (2002a), with bird dispersed seeds giving it the potential to become even more widespread. At the time of writing, C. nocturnum was not found on the northern Cook Islands, or the southern Cook Islands of Miti'aro, Ma'uke, 'Atiu and Aitutaki (Space & Flynn, 2002a); PIER (2010) lists a specimen of C. nocturnum collected on Aitutaki in 1960, but this is not mentioned in Space & Flynn (2002a). C. nocturnum has been observed in the understory of relatively undisturbed native forest in Rarotonga up to 400m - 500m (Meyer, unpubl. data.; in Meyer, 2004) and is thought to be one of the species that has driven the rare endemic Acalypha wilderi to possible extinction through competition (McCormack, pers. comm., 2000; in Meyer, 2004).
