I stand to be corrected, but I believe this mistletoe is Amyema and most probably benthamii. I came across it in Minyirr Park, where it is known to grow on Exocarpos latifolius and Atalaya hemiglauca. Unfortunatley I cant recall what it was growing on. This photo was taken mid December, so maybe I was too distracted by the christmas cheer of the red, green, yellow flowers.
This species grows on a variety of hosts across different genus’ including; Mallotus, Hakea, Grewia, Terminalia, Ficus, Acacia, Croton & Brachychiton.
It occurs widely throughout the Kimberley and also in other parts of WA. See florabase map. http://florabase.calm.wa.gov.au/browse/profile/2369
